❶ 5G币投资可靠吗是骗人的吗

主流数字货币行情现在都不好，还玩传销币割你没商量，小心本金哦！

❷ 币圈staking是什么意思

币圈Staking其实是一种持币生息的商业模式，即代币持有者通过质押、投票、委托和锁定代币等行为获取区块奖励以及分红等收益。通俗一点讲，就是一种持币者“以币生币”的投资方式，有点类似于银行的储蓄生息(持币生息)，所以我们通常叫它POS权益质押经济。
在POS或者类似于POS机制中任何人都可以通过加密资产抵押锁仓赚币，收益率是以币本位计算，收益率的大小依赖于加密资产的通胀模型。今年比较火热的ATOM和XTZ就采用了Staking的模式，下图就是一些加密资产staking的年化收益率。而在今年下半年到明年，以太坊2.0和ADA等项目都会开启Staking。
最开始的加密资产大多都是模仿的BTC采用的POW机制，即工作量证明机制，区块链网络中的节点是一台台的矿机，需要依靠算力获得区块奖励，对能源浪费比较大。而Staking说白了就是抵押资产挖矿，抵押的资产越多，获得的效益也就越高。
不过相对来说都有一定的参与门槛，而对于新人来说也不会识别到底是噱头还是真的Staking，不过这是未来的一个新趋势。去年炒作的比较火的EOS超级节点竞选，那些超级节点需要锁仓一定量的EOS，就能获得EOS每年的增发奖励，这也算属于Staking。
BTM的侧链Bystack采用的Dpos机制，参与竞选的节点需要有100万枚BTM，成为节点之后这些BTM将会锁仓，节点将会获得一定量的BTM奖励，这也是Staking。
参与质押的方式一般有两种：第一种就是通过主网的官方钱包或者imtoken等去中心化钱包来质押，这种质押方式比较安全，只是在权益层面上进行了链上委托，私钥不会泄露；另外一种就是把币放到中心化钱包或者矿池，如火币矿池就支持很多币种的权益质押，不过相当于把自己的币给别人保管，安全性上不如第一种，不过门槛要相对低点。

❸ 币圈ido是什么意思

IDO即“InitialDigitalAssectsOffering”，意思是首次区块链数字资产的发行。这一说法源自股票市场的首次公开发行(IPO)概念，是企业区块链项目首次以资产数字化产生出来的区块链数字资产，以产品锚定，资产债券、众筹方式筹集的通用数字资产的行为。

IDO是以“资产通证”为交易核心的一种数字资产交易模式。IDO(首次资产通证要约回购式发行)最大的意义在于发行数字资产的发行方以要约回购的方式保证首次发行的投资本金安全。

一、币圈ICO是什么意思
ICO是区块链行业内项目通过主流比特币、以太坊等数字资产募集资金的常用方式，其概念也是从股票市场IPO衍生过来的。

二、IDO和ICO的不同之处
1、简单来说，IDO本身不募集资金，而是通过发起任务悬赏的方式，让看重项目价值的用户，自发地利用自己的知识、时间、注意力等技能来获得项目方的TOKEN悬赏激励。

2、IDO有点像ICO的升级版，本质上两者的项目团队都有锁定代币。不同的是ICO首次发行就筹集了用户的资金进行项目建设，而IDO则是不筹集资金，把社区建设分发给用户，让大家一起来建设社区项目的发展。

3、IDO有设法绕过监管的嫌疑。因为ICO时代是用大家的资金来发展项目，IDO时代是用大家的资源来发展项目，两者本质差不多。此外如果项目的通证经济设计的不合理，IDO便和积分币区别不大。
不过虽然有以上不同，但是他们都有通过出售股份来筹措资金；都有潜在投资者为了潜在的巨大收益而冒险参与。

❹ 币圈bsc是什么意思呢

BSC币的全称是BSCToken，供应总量为100000万BSC。BSC币成为国内实体链改革的第一个模式。BSC币将基于以美丽南方田园综合体为代表的实物资产支持登记、流通、抵押借贷等各类证券化通证，成为区块链价值释放的新模式，构建潜力无限的全球旅游价值交换生态系统，为中国区块链奠定了一定的发展基础。”
拓展资料
设计平衡计分卡的目的就是要建立“实现战略制导”的绩效管理系统，从而保证企业战略得到有效的执行。因此，人们通常称平衡计分卡是加强企业战略执行力的最有效的战略管理工具。
平衡计分卡创建绩效
平衡计分卡能有效解决制定战略和实施战略脱节的问题，堵住了“执行漏斗”。平衡计分卡系统则包括战略地图、平衡计分卡以及个人计分卡、指标卡、行动方案、绩效考核量表。在直观的图表及职能卡片的展示下，抽象而概括性的部门职责、工作任务与承接关系等，显得层次分明、量化清晰、简单明了。
平衡计分卡时期
该阶段Robert Kaplan与David Norton研究的结论“平衡计分卡：驱动绩效的量度”发表在92年《哈佛商业评论》一月与二月号，基本上，平衡计分卡强调，传统的财务会计模式只能衡量过去发生的事项（落后的结果因素），但无法评估企业前瞻性的投资（领先的驱动因素），因此，必须改用一个将组织的愿景转变为一组由四项观点组成的绩效指标架构来评价组织的绩效。此四项指标分别是：财务（Financial）、客户（Customer）、内部运营（Internal Business Processes）、学习与成长（Learning and Growth）。
藉着这四项指标的衡量，组织得以明确和严谨的手法来诠释其策略，它一方面保留传统上衡量过去绩效的财务指标，并且兼顾了促成财务目标的绩效因素之衡量；在支持组织追求业绩之余，也监督组织的行为应兼顾学习与成长的面向，并且透过一连串的互动因果关系，组织得以把产出（Outcome）和绩效驱动因素（Performance Driver）串联起来，以衡量指标与其量度作为语言，把组织的使命和策略转变为一套前后连贯的系统绩效评核量度，把复杂而笼统的概念转化为精确的目标，藉以寻求财务与非财务的衡量之间、短期与长期的目标之间、落后的与领先的指标之间，以及外部与内部绩效之间的平衡。

❺ 币圈和链圈的区别是什么

链圈”、“币圈”、“矿圈”不少人傻傻分不清楚，但撇开那些关联，三者的本质其实还是大相径庭的。在区块链生态中，目前大致划分为三个圈，分别为“链圈”、“币圈”、“矿圈”。三者相互关联，却也大有区别，
链圈——链圈，技术派的代表。门槛相较于其他两个圈更高，主要专注于区块链技术的发展与应用，所以对于普通人来说，比较难跨进去。
区块链可以分为三阶段：私有链、公有链和联盟链。
币圈——币圈，可以说是最丰富多彩的一个圈。专注于炒加密数字货币，为三圈中入门门槛最低的圈。主要特点为发币和炒作，基于区块链技术发行的币为主流币，如比特币、以太坊等，风险较小。而ICO发行的币，则为山寨币，存在一定风险，炒作则是因为行业缺乏监管，后台操盘常见造成，目前我国已禁止ICO。
矿圈——矿圈，是专注于“挖矿”的一群人所在的圈子。这个挖矿不同于生活中的挖矿，而是为了获得虚拟货币奖励所进行的一种行为，参与挖矿的人，则被称之为矿工。
挖矿需要借助工具，早期通过一般电脑即可挖矿，之后随着挖矿人数的不断增加，开始发展成矿机挖矿，矿池挖矿。挖矿所需付出的成本较高，比如耗电巨大，电费也是一笔不小的支出。
矿圈的门槛略高于币圈，但低于链圈。大部分人都听过挖矿，但真正参与挖矿的人还是较少。
而相比链圈和币圈，矿圈还会受到外部自然环境的影响，如矿场矿机遭到损坏等。
现在的大背景下，炒作区块链的概念已经毫无意义了。区块链从业者一定是要想办法为这个社会贡献价值，去创造财富，而不是蒸发财富，所以我们不区别币圈、链圈，能创造价值的就是好圈。

❻ 虚拟货币、数字货币、加密货币、代币、通证有什么区别

一、定义不同：

1.虚拟货币：

虚拟货币为指非真实的货币。

2.数字货币：

数字货币为电子货币形式的替代货币。数字金币和密码货币都属于数字货币（DIGICCY）。

3.加密货币：

加密货币为一种使用密码学原理来确保交易安全及控制交易单位创造的交易媒介。

4.代币（通证）：

一种形状及尺寸类似货币，但限制使用范围、不具通货效力的物品，其通证则为代币英文Token的谐音。

二、特点不同：

1.虚拟货币：

虚拟货币不是一般等价物，而是价值相对性的表现形式，或者说是表现符号；也可以说，虚拟货币是个性化货币。在另一种说法中，也可称为信息货币。

2.数字货币：

是一种不受管制的、数字化的货币，通常由开发者发行和管理，被特定虚拟社区的成员所接受和使用。

3.加密货币：

加密货币基于去中心化的共识机制，与依赖中心化监管体系的银行金融系统相对。

4.代币（通证）：

通常需要以金钱换取，用在商店、游乐场、大众运输工具等地方，做为凭证以使用服务、换取物品等。

(6)圈币模式扩展阅读

现阶段数字货币更像一种投资产品，因为缺乏强有力的担保机构维护其价格的稳定，其作为价值尺度的作用还未显现，无法充当支付手段。数字货币作为投资产品，其发展离不开交易平台、运营公司和投资。

数字货币是一把双刃剑，一方面，其所依托的区块链技术实现了去中心化，可以用于数字货币以外的其他领域，这也是比特币受到热捧的原因之一；另一方面，如果数字货币被作为一种货币受到公众的广泛使用，则会对货币政策有效性、金融基础设施、金融市场、金融稳定等方面产生巨大影响。

❼ 区块链有哪些生态圈

加密货币发展到今天，带火了“区块链技术”、区块链技术的发展成了众望所归。在我国，无论是BATJ(网络、阿里、腾讯、京东)这样的巨头公司，还是滴滴、OFO小黄车这样“新军突起”的公司，都在积极探索区块链技术。纵观全世界，沃尔玛、万事达卡、
IBM、巨头汽车制造厂商都在尝试使用区块链技术解决行业痛点。此外，还有诸如日本柯达公司这种“江河日下”的企业希望通过区块链打一场“翻身仗”。
这些现象说明了什么呢，说明区块链这个技术，有着非常大的商业价值，谁都希望能在这片未知的土地上开垦出一片新天地。所以，区块链技术发展到今年呢，已经不仅仅是单纯的底层技术了，而是形成了一套完整的生态系统，下面我们就从“币圈”和“链圈” 两个方面跟大家聊一聊：区块链的生态圈是怎么样的，带大家了解区块链行业的一个全貌。
第一节币圈
在币圈，始终要不开这几个名词：项目方、交易所、媒体、矿机厂商，接下来呢，咱们就来详细盘点一下是怎么回事。
一、项目方
币圈的项目方可以这么理解：凡是发token的都是项目方。注意，是币圈。也有一些项目方不发币的，比如说阿里、腾讯、网易这些也在做区块链项目的项目方，他们是不发币的，只专注于技术，那这些不发币的项目方呢，主要侧重区块链在数据安全、供应链方面的作用，这些我们后面会提到。
再回到币圈项目方这个话题，比如说最近争议比较大的亦来云、之前的波场，这些都是币圈的项目方，还有最近比较热的区块链游戏，在游戏里面赚token这种，他们也属于币圈项目方。
币圈项目一个颠覆的地方是，把项目和代币结合在一起，直接用代币代替了股权，而且代币可以直接流通。这一点是一个非常具有革命性的，让很多初始项目，可以更加方便的融资，融资之后，反馈的代币能上数字货币交易平台流通，投资方也可以很好的退出。
这种“融资-投资”的方式似乎是以另外一种方式，变相实现了股权上市交易流通。
所以呢，正是这样一种模式，让币圈项目方成为一个离钱最近的地方，他们很容易圈钱，当然也很容易禁不住诱惑，或者蓄谋已久，圈了钱就跑路。项目方发token的详细流程一般是这样的：
第一步是做好一套token系统，这就类似于做一个app应用，这点不是很复杂，因为以太坊都是开源的，类似于安卓苹果系统，开发者可以在上面开发具体的应用；
第二步就是写一份白皮书，这就类似于商业计划书，白皮书类似于商业计划书，主要包括项目的团队情况、技术情况等信息；
第三步要找人做背书，找一些有影响力的业界大咖来宣传宣传；
第四步开始推广营销，找一些区块链媒体推软文，拉合作，这个我们下面会提到；
第五步是找融资；
第六步上交易所，token开始大范围流传。
二、交易所
说完项目方，我们来说交易所。如果说项目方是生产者，那么，他们生产出来的东西得去销售、去做交易，对不对？交易所就是项目方token的一个交易场所。如果说项目方的token类似于股票，那么币圈的交易所就类似于股市的二级市场吧。只不过币圈的交易所权力更多一些，有上币审核权，可以决定上币或者下币。
当然，项目方想上币，要支付给交易所巨额的上币费用，投资者在交易所里面交易呢，也需要付手续费或提现费，每家交易所手续费提现费规则都不太一样。那其实，上币费、手续费、提现费就构成了币圈交易所的盈利模式，当然，除了这三种盈利模式，交易所的盈利模式还有：“做市商”业务赚取差价，也就是交易所通过不断买卖，创造流动性，充当做市商，同时赚取业务差价。
目前，由于行业竞争越来越激烈，上币费和手续费将越来越少，甚至不需要，所以常规盈利所占的比重会越来越少，这就出现了其他的盈利模式，比如说：平台币、杠杆手续费。先来说说平台币。平台币就是交易所发的币：OKB、币安币都属于平台币，交易所发放的这些平台币可以换取BTC、ETH，同时呢，平台币自身价值的增值，可以为交易所的发展奠定坚实的物质基础，对用户而言，持有平台币可以享受到手续费折扣、平台分红、交易所的专项活动等好处，这是平台币。杠杆手续费呢，就是平台上的融币功能，支持杠杆交易，并向融币用户收取一定比例的手续费。
上面说的这些其实都是通过交易所自身资源输出而构建的生态系统。现在，交易所还在积极布局全行业来获得收入，比如：成立资本、矿池、钱包、孵化器、工程院、基金等方式。我们认为，如果交易所想长久发展下去，就必须全产业链布局，找到行业的新爆发点，构建完整生态系统，所以，把战略盈利的比重变大。
三、区块链媒体
在区块链火爆的这两年，不止项目方非常多，媒体也如同雨后春笋一般出现了，目前比较知名的区块链媒体大概有200来家吧。区块链媒体平台上的内容大概就是围绕这么几点：政策、黑客、交易所、大佬、项目方。文字之外，区块链媒体的运营方式还包括社群活动，比如说：邀请“大佬”进群做分享，以这种方式达到优质内容的一个沉淀，同时赚取一些流量。
为什么一定要提区块链媒体呢，是因为，区块链媒体和我们印象里面的媒体其实是有些区别的。区别在哪里呢？区别就在于：区块链媒体和上面提到的项目方、交易所，这三者之间存在着一些利益关系。我们刚刚说，项目方好比“生产者”，交易所好比“销售市场”，那么，媒体扮演的角色呢，就好比“广告平台"。项目想要卖得好，需要宣传，需要打广告，那么区块链媒体就扮演了这么一个角色，所以，现在一些区块链媒体的投资方正是项目方、交易所。
最近这段时间是熊市，多家区块链媒体大规模裁员，究其原因无非是项目短缺，资金不足。所以呢，如果说区块链媒体单纯依靠项目方、交易所的投资、以及广告收入，其实是远远不够的，当熊市来临，项目方、交易所受到波及了，那么媒体势必也将面临非常残酷的寒冬。因此，现在很多区块链媒体也在做项目方发token（最典型的的就是币乎、币车这种内容社区，他们既属于一种媒体平台，又在发token做项目方）、或者有些区块链媒体在做钱包、卖矿机租算力这些业务。
但是，我们认为，区块链媒体，作为媒体，毕竟还是发挥舆论引导作用的，所以呢，还是要回归本质，做行业价值信息的一个传递场所，而不是一个堆砌广告的地方。因此呢，区块链媒体还是应该跟上技术的发展，来实现自身的生存和发展，凭借区块链技术的优势，基于通证系统中的共识机制，去实现媒体行业利益的合理分配，在这个方面呢，或将具有一定的想象空间。
四、矿机厂商
比特币挖矿说到底是算力的竞争，谁的算力强大，谁挖到比特币的几率就越大。所以，在整个币圈的商业系统里面，矿机厂商是一个非常不可忽视的存在。我们看一个数据就知道了：2018年胡润百富榜区块链行业里面，排在首富的就是来自矿机厂商——比特大陆的合伙人，詹克团先生。另外，根据招股书，比特大陆上半年净利润7.43亿美元，同比增涨了近8倍，它一度占据全球比特币矿机70%以上的市场份额，成为矿机行业龙头。不止矿机，比特大陆在矿池（也就是一种合作挖矿的模式）方面依旧占据了近乎垄断的地位：就目前来看，全球前六大矿池算力占79.2%的份额。
而另一家研究矿机芯片的公司——“嘉楠耘智”，在发明中国第一台比特币矿机之后，开始从事区块链、人工智能领域芯片的研究，短短几年，也成为国际知名的芯片企业。
其实，早在2012年，美国就宣布要发售一台蝴蝶矿机，但是这个事情后来被很多人认为是一场骗局，因为这个蝴蝶矿机拖了好几年才发售，这几年还让其他国家的矿机研发变得非常惶恐，都在拼命抢时间，某种意义上来说，蝴蝶矿机也算是带动了矿机行业的繁荣。所以呢，到了2013年，矿机就已经进入一个百花争鸣的季节，大量ASIC矿机就被提出来了：或宣布研发，或宣布预售，或以现货形式，出现了：烤猫矿机，鸽子矿机，TMR 矿机，比特儿矿机，兰德矿局，小蜜蜂矿机，阿瓦隆原厂和各种代工，花园矿机，Smart 矿机等等......可能大家没听过这些矿机，因为这些基本上都死了，留下来的比特大陆、嘉楠耘智、亿邦股份,成为了矿机巨头。
不过，矿机，作为加密货币市场繁荣下的衍生产业，它的价格和加密货币市场行情是息息相关的：在牛市，矿机常常供不应求，矿工们花数倍高价从“黄牛”手中购买矿机屡见不鲜，这个时候，矿机厂商进入红利期。但是在熊市呢，矿机厂商也将受到一些不利影响，矿工挖矿热情减退，一些厂商不得不降低矿机价格来收回成本。譬如，在今年三月比特币暴跌时，华强北售卖的某型号矿机降价5000元甩卖，价格由每台19000元左右降至
14000元。
【总结】
讲到这里，我们可以发现，无论是项目方、交易所、媒体，还是矿机，可以说是一种 “一荣俱荣一损俱损”的关系。牛市里，项目方拿融资有钱发token，上到交易所，交易所赚到了上币费和交易费，token 身家增加还能让项目方再赚一笔，然后找媒体投放广告，媒体赚到广告费，那么币价高了，矿工热情高涨，矿机也卖得好了。但是到熊市呢，完全
是一个相反的迹象，大家都在面临寒冬，所以说，这是一个“一荣俱荣一损俱损”的关系。
币圈先介绍到这里，下面我们来介绍一下链圈。
第二节链圈
链圈，指的是关注区块链技术的圈子。和币圈相比，链圈就显得相当低调。但是呢，没有链圈的技术支撑，币圈也不可能存在。所以，链圈常常被忽视，但是其实它非常重要，未来区块链场景的落地，还要依靠链圈的技术作为支撑。
目前，链圈项目主要围绕的是供应链中的数据安全这个方面来开展的。我们在开头提到得沃尔玛、万事达卡、IBM、还有那些巨头汽车制造厂商，他们在尝试使用区块链技术解决一些涉及到数据安全的行业痛点，譬如说：生鲜食品的流通安全、疫苗安全、交易数据安全、版权保护等等。
在供应链方面，最典型的当属快递行业，顺丰目前正试图用区块链技术解决药品物流安全。此外，阿里正在雄安新区积极部署区块链；腾讯、网络、网易、京东已经开发了多款基于区块链的网络游戏，尽管这些项目目前还并不是很成熟，但是却丰富了区块链的商业模式，提供了一些比较广阔的想象空间。
提到想象空间，对于链圈来讲，其实主要围绕的就是“区块链+”这个话题：区块链+ 金融、区块链+保险、区块链+农业、区块链+娱乐、区块链+人工智能，区块链+等等任何的行业......说白了就是区块链场景的落地，把这些想象变成现实，就好比把互联网普及到千家万户一样。
【总结】
区块链这个底层技术，最早其实就是一个货币系统，为了比特币服务的嘛，但是发展到今天呢，这种技术已经演变成一种变革和创新的思路或者方法了，这些思路和方法也确实是目前互联网时代一些痛点的解决之法。

❽ 关于币圈，有哪些是需要我们了解的

如果你刚刚入坑币圈，正欲入手数字货币，别着急，先静下心来看一看下面的内容，我猜一定会对你有所帮助。

一、什么是数字货币钱包
很多人说，数字货币钱包就是用来装数字货币的，通俗来讲这样理解没有问题，但实际上，数字货币钱包装的并不是数字货币，而是装密钥（私钥和公钥）的工具，有了密钥就可以拥有相应地址上的数字货币的支配权，利用钱包中生成的数字货币收款地址，可以接受他人给你转账的数字货币，也可以把你所拥有的数字货币转账给其他人。通俗来讲可以理解为用来存储和交易数字货币。

二、数字货币钱包的结构
1、地址：
钱包地址是一串字符串，作用是用来转账，钱包地址可以理解成银行卡卡号，可以告诉任何人，知道你钱包地址的任何人都可以给你的钱包地址转数字货币，不同的数字货币地址也是不同的，比如eos和btc的地址并不一样。
2、私钥
私钥是由系统根据用户环境中的随机因数，通过密码学算法生成的随机数。可以把它看成是银行卡密码，每次交易，付款方必须出具私钥，以及私钥产生的签名。
3、公钥
公钥是由私钥生成的，和私钥成对儿出现，公钥可以算出地址，主要用来生成地址。
4、密码
在创建钱包时，需要设置一个密码，密码的使用主要是：1.转账时的支付密码；2.导入钱包时需要验证密码。密码是用户主动设置的，但是安全性远低于私钥。密码主要起到双重保护的作用。
5、助记词
助记词是私钥的另一种表现形式，功能等同于私钥，助记词一般为12-15个或更多个英文单词组成，通过助记词就能找到私钥，还原钱包，因此助记词很重要，大多数钱包会提示用户备份助记词，以便恢复钱包。

三、数字货币钱包的分类
大体上可分为两大类，热钱包（在线钱包）和冷钱包（离线钱包）
（一）热钱包：
又称在线钱包，包含轻钱包和重钱包（全节点钱包），需保持连网上线的钱包，可以直接进行交易操作。
1、轻钱包：
不储存完整的区块链，只保存和自已相关的数据。它的体积小，可以在手机、电脑、网页等运行。
优缺点：不占用内存、支持多种数字资产、用户体验好、新手上手快，但交易验证稍慢

2、重钱包（全节点钱包）
维护着全部的区块链数据，完全去中心化，同步所有数据。具有更好的隐私性、可以在本地验证交易数据的有效性。
热钱包的优缺点：具有更好的隐私性、验证信息更快速，但每次使用都需要前需要同步数据，占用很大的硬盘空间，不支持多种数字货币交易。
（二）冷钱包：
冷钱包就是不连网的钱包，也叫离线钱包；比如专业的硬件设备，或者将私钥（助记词）写在纸上。
1、硬件钱包
硬件钱包即是用专业的硬件存储数字货币，将数字资产私钥单独储存在一个芯片中，与互联网隔离，即插即用。
2、纸钱包
把私钥写在纸上存储，再删除

冷钱包的优缺点：相对比较安全，但创建钱包和交易都非常麻烦，对于新手来说操作比较困难，钱包价格都相对昂贵，一般从几千到上万元不等。如果没有太大额的数字资产，可以不用考虑。

四、如何选择数字货币钱包
轻钱包使用起来更简单便捷，一般都支持多币种，一般适合新入币圈的小白或交易和存储量不大的用户使用。比如极客钱包（geekwallet）
硬件钱包不联网，安全性更高，但操作相对复杂，一般适合交易和存储量比较大的用户。

五、使用数字货币钱包时的注意事项

1、保管好密码，一旦丢失，不能找回。不过可以通过助记词重置密码（前提是安全保管好助记词）。
2、保管好私钥，私钥拥有者才是比特币真正的拥有者。
3、保管好助记词，一但别人拿到这个助记词，别人就能把助记词对应钱包内的区块链资产全部转走。

❾ 币圈ICO是什么

币圈就是关于数字货币（虚拟货币）发行、交易、炒作以及相关的一切活动，还有参与的个人用户或者机构。数字货币常见的有比特币、莱特币等，这里比特币是人们听说最多的，而且在平时很多人参与比特币的买卖。比特币在2008年由中本聪提出，总数量只有2100万个，它的发行不依靠任何机构。随着比特币不断被挖掘，越往后产生比特币的难度会增加，可能获得比特币的成本要比比特币本身的价格高。

❶ Is 5G coin investment reliable? Is it a lie?

The mainstream digital currency market is not good right now. If you are still trying to cut coins in a pyramid scheme, you have no objection. Be careful with your principal!

❷ What does staking in the currency circle mean?

Staking in the currency circle is actually a business model that earns interest by holding currency, that is, token holders use staking, voting, delegation and locking tokens. You can obtain block rewards, dividends and other benefits through actions such as coins. In layman's terms, it is an investment method in which currency holders "generate currency with currency", which is somewhat similar to a bank's savings and interest earning (interest earned by holding currency), so we usually call it the POS equity pledge economy.
In POS or similar POS mechanisms, anyone can earn coins by staking crypto assets and locking positions. The rate of return is calculated on a currency basis, and the size of the rate of return depends on the inflation model of crypto assets. ATOM and XTZ, which are relatively popular this year, have adopted the staking model. The figure below shows the annualized yield of staking of some crypto assets. From the second half of this year to next year, projects such as Ethereum 2.0 and ADA will start staking.
Most of the earliest crypto assets imitated the POW mechanism used by BTC, that is, the proof-of-work mechanism. The nodes in the blockchain network are mining machines that rely on computing power to obtain block rewards. Energy waste is relatively large. To put it bluntly, Staking is mining by mortgaging assets. The more assets you mortgage, the higher the benefits you will get.
However, relatively speaking, there is a certain threshold for participation, and newcomers will not be able to distinguish whether it is a gimmick or real staking, but this is a new trend in the future. The EOS super node election was highly hyped last year. Those super nodes need to lock up a certain amount of EOS to receive the annual additional issuance reward of EOS. This is also considered staking.
BTM's side chain Bystack adopts the Dpos mechanism. Nodes participating in the election need to have 1 million BTM. After becoming a node, these BTM will be locked, and the node will receive a certain amount of BTM rewards. This is also Staking.
There are generally two ways to participate in staking: the first is to pledge through the official wallet of the main network or a decentralized wallet such as imtoken. This staking method is relatively safe, and it only performs on-chain delegation at the equity level. The private key will not be leaked; the other option is to put the coins in a centralized wallet or mining pool. For example, Huobi Mining Pool supports the equity pledge of many currencies, but it is equivalent to giving your own coins to others for safekeeping, and is not as safe as The first type, but the threshold is relatively low.

❸ What does ido mean in the currency circle?

IDO is "InitialDigitalAssectsOffering", which means the first issuance of blockchain digital assets. This statement originates from the concept of initial public offering (IPO) in the stock market. It is the first blockchain digital asset produced by an enterprise blockchain project through asset digitization.Product anchoring, the behavior of general digital assets raised through asset bonds and crowdfunding.

IDO is a digital asset trading model with "asset certificate" as the core of the transaction. The greatest significance of IDO (Initial Asset Token Offer and Repurchase Issuance) is that the issuer of digital assets ensures the safety of the investment principal in the initial issuance through a repurchase offer.

1. What does ICO mean in the currency circle?
ICO is a common way for projects in the blockchain industry to raise funds through mainstream digital assets such as Bitcoin and Ethereum. Its concept is also derived from the stock market IPO. of.

2. The differences between IDO and ICO
1. To put it simply, IDO itself does not raise funds. Instead, it allows users who value the value of the project to spontaneously use themselves by launching task bounties. Knowledge, time, attention and other skills to obtain TOKEN reward incentives from the project side.

2. IDO is a bit like an upgraded version of ICO. Essentially, both project teams have locked tokens. The difference is that the first issuance of ICO raised user funds for project construction, while IDO did not raise funds, but distributed community construction to users, allowing everyone to work together to build the development of community projects.

3. IDO is suspected of trying to circumvent supervision. Because in the ICO era, everyone’s funds are used to develop projects, while in the IDO era, everyone’s resources are used to develop projects. The essence of the two is similar. In addition, if the project's token economic design is unreasonable, IDO will not be much different from the point currency.
However, despite the above differences, they all raise funds by selling shares; all potential investors take risks for the potential huge gains.

❹ What does bsc mean in the currency circle?

The full name of BSC coin is BSCToken, and the total supply is 1,000,000,000 BSC. BSC currency has become the first model of domestic physical chain reform. Based on the physical assets represented by the Beautiful Southern Pastoral Complex, BSC currency will support various securitization tokens such as registration, circulation, mortgage lending, etc., becoming a new model for blockchain value release, and building a global tourism value exchange ecosystem with unlimited potential. , laying a certain foundation for the development of China’s blockchain. ”
Extended information
The purpose of designing the balanced scorecard is to establish a performance management system that “realizes strategic guidance” to ensure the effective execution of corporate strategies. Therefore, people usually call the balanced scorecard a tool to strengthen the enterprise The most effective strategic management tool for strategic execution.
Balanced Scorecard Creates Performance
Balanced Scorecard can effectively solve the problem of disconnection between formulating strategy and implementing strategy, blocking the "execution funnel". Balanced Scorecard The card system includes strategic maps, balanced scorecards, personal scorecards, indicator cards, action plans, and performance appraisal scales. Under the display of intuitive charts and functional cards, abstract and general department responsibilities, work tasks and Undertaking relationships, etc., appear to be clearly hierarchical, clear in quantification, and simple and clear.

In this stage, the conclusions of Robert Kaplan and David Norton's study "The Balanced Scorecard: Measures that Drive Performance" were published in the January and February issues of Harvard Business Review in 1992. Basically, the Balanced Scorecard Emphasize that the traditional financial accounting model can only measure events that have occurred in the past (laggy outcome factors), but cannot evaluate the company's forward-looking investments (leading drivers). Therefore, it is necessary to use a model to transform the organization's vision into a set of A performance indicator framework consisting of four perspectives to evaluate organizational performance. The four indicators are: Financial, Customer, Internal Business Processes, and Learning and Growth.
Through the measurement of these four indicators, the organization can interpret its strategy in a clear and rigorous way. On the one hand, it retains the traditional financial indicators that measure past performance, and also takes into account the measurement of performance factors that contribute to financial goals; In addition to supporting the organization's pursuit of performance, it also supervises the organization's behavior to take into account learning and growth. Through a series of interactive causal relationships, the organization can connect output (Outcome) and performance drivers (Performance Driver) to measure Indicators and their measurements serve as language to transform the organization's mission and strategy into a coherent set of systematic performance evaluation measures, and to transform complex and general concepts into precise goals, thereby seeking to find a balance between financial and non-financial measurement, short-term and The balance between long-term goals, between lagging and leading indicators, and between external and internal performance.

❺ What is the difference between currency circles and chain circles

Many people are stupid about "chain circles", "coin circles" and "mining circles" It’s hard to tell the difference, but aside from those connections, the essences of the three are actually quite different. In the blockchain ecosystem, it is currently roughly divided into three circles, namely the “chain circle”, “coin circle” and “mining circle” . The three are related to each other, but they are also very different.
Chain Circle - Chain Circle, the representative of the technical school. The threshold is higher than the other two circles, and it mainly focuses on the development and application of blockchain technology. , so it is more difficult for ordinary people to get in.
Blockchain can be divided into three stages: private chain, public chain and alliance chain.
Coin circle-coin circle, can be said to be the most A colorful circle. It focuses on speculating on encrypted digital currencies and is the circle with the lowest entry barrier among the three circles. The main characteristics are currency issuance and speculation. The coins issued based on blockchain technology are mainstream currencies, such as Bitcoin, Ethereum, etc. , the risk is smaller. The coins issued by ICO are altcoins, which have certain risks. The hype is caused by the lack of supervision in the industry and common back-end trading. Currently, ICO has been banned in China.
Mining Circle - Mining Circle , is a circle of people who focus on "mining". This mining is different from mining in life, but to obtain virtualAn act performed with pseudo-monetary rewards, and those who participate in mining are called miners.
Mining requires the use of tools. In the early days, mining could be done through ordinary computers. Later, as the number of miners continued to increase, it began to develop into mining machine mining and mining pool mining. Mining requires high costs, such as huge power consumption, and electricity bills are also a large expense.
The threshold of the mining circle is slightly higher than that of the currency circle, but lower than that of the chain circle. Most people have heard of mining, but there are still fewer people who actually participate in mining.
Compared to the chain circle and the currency circle, the mining circle is also affected by the external natural environment, such as damage to the mining machine in the mine.
In the current context, it is meaningless to hype the concept of blockchain. Blockchain practitioners must find ways to contribute value to this society and create wealth instead of evaporating wealth. Therefore, we do not distinguish between currency circles and chain circles. Those who can create value are good circles.

❻ What are the differences between virtual currency, digital currency, cryptocurrency, token, and pass

1. Different definitions:

1. Virtual currency: < /p>

Virtual currency refers to non-real currency.

2. Digital currency:

Digital currency is an alternative currency in the form of electronic currency. Digital gold coins and cryptocurrency are both digital currencies (DIGICCY).

3. Cryptocurrency:

Cryptocurrency is a trading medium that uses cryptographic principles to ensure transaction security and control the creation of trading units.

4. Token (pass):

An item that is similar in shape and size to currency, but has a limited scope of use and has no currency effect. Its token is a token in English The homophony of Token.

2. Different characteristics:

1. Virtual currency:

Virtual currency is not a general equivalent, but an expression of relative value. In other words, it is a symbol of expression; it can also be said that virtual currency is personalized currency. In another way, it can also be called information currency.

2. Digital currency:

It is an unregulated, digital currency, usually issued and managed by developers, and accepted and used by members of specific virtual communities.

3. Cryptocurrency:

Cryptocurrency is based on a decentralized consensus mechanism, as opposed to the banking financial system that relies on a centralized regulatory system.

4. Tokens (tokens):

Usually required to be exchanged for money and used as vouchers in stores, amusement parks, public transportation, etc.To use services, exchange items, etc.

(6) Extended reading on currency circle model

At this stage, digital currency is more like As an investment product, due to the lack of a strong guarantee institution to maintain the stability of its price, its role as a measure of value has not yet emerged and it cannot serve as a means of payment. As an investment product, the development of digital currency is inseparable from trading platforms, operating companies and investments.

Digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on is decentralized and can be used in other fields besides digital currency. This is why Bitcoin is so popular. One of the reasons; on the other hand, if digital currency is widely used by the public as a currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial markets, financial stability, etc.

❼ What are the ecosystems of blockchain?

The development of cryptocurrency to this day has made "blockchain technology" popular, and the development of blockchain technology has become what everyone expects. In our country, both giant companies such as BATJ (Network, Alibaba, Tencent, JD.com) and "new emerging" companies such as Didi and OFO are actively exploring blockchain technology. Throughout the world, Walmart, Mastercard,
IBM, and giant automobile manufacturers are all trying to use blockchain technology to solve industry pain points. In addition, there are companies such as Japan's Kodak that are in decline and hope to fight a "turnaround" through blockchain.
What do these phenomena indicate? It shows that the blockchain technology has great commercial value, and everyone hopes to open up a new world in this unknown land. Therefore, with the development of blockchain technology this year, it is no longer just a simple underlying technology, but has formed a complete ecosystem. Below we will tell you about it from the two aspects of "currency circle" and "chain circle" Let’s talk about: What is the blockchain ecosystem like? Let’s take you to understand the whole picture of the blockchain industry.
Section 1: Currency Circle
In the currency circle, these terms are always important: project parties, exchanges, media, and mining machine manufacturers. Next, let’s take a detailed inventory of how Something happened.
1. Project Party
The project party in the currency circle can be understood this way: anyone who issues tokens is the project party. Note, it is a currency circle. There are also some project parties that do not issue coins, such as Alibaba, Tencent, and NetEase, which are also working on blockchain projects. They do not issue coins and only focus on technology. What about these project parties that do not issue coins? It mainly focuses on the role of blockchain in data security and supply chain, which we will mention later.
Going back to the topic of project parties in the currency circle, for example, the recently controversial Elastos and the previous TRON are all project parties in the currency circle, as well as the recently popular blockchain games. They also belong to the currency circle project side when it comes to earning tokens in games.
A subversive aspect of the currency circle project is that, combining projects and tokens, directly replacing equity with tokens, and tokens can be directly circulated. This is a very revolutionary feature that allows many initial projects to more easily raise funds. After financing, the feedback tokens can be circulated on digital currency trading platforms, and investors can also exit well.
This "financing-investment" approach seems to be another way to realize the circulation of equity listings and transactions in disguise.
So, it is this kind of model that makes the currency circle project team the place closest to money. It is easy for them to trap money. Of course, it is also easy for them to be tempted, or have planned for a long time, and run away after trapping money. road. The detailed process for project parties to issue tokens is generally as follows:
The first step is to build a token system, which is similar to making an app application. This is not very complicated because Ethereum is open source. Similar to Android and Apple systems, developers can develop specific applications on it;
The second step is to write a white paper, which is similar to a business plan. The white paper is similar to a business plan and mainly includes the team situation of the project. , technical status and other information;
The third step is to find someone to endorse and find some influential industry figures to promote it;
The fourth step is to start promotion and marketing, find some blockchain media to promote Soft articles, cooperation, we will mention this below;
The fifth step is to find financing;
The sixth step is to go to the exchange, and the token begins to spread widely.
2. Exchange
After talking about the project side, let’s talk about the exchange. If the project party is a producer, then the things they produce must be sold and traded, right? The exchange is a trading place for project party tokens. If the project team's token is similar to a stock, then the exchange in the currency circle is similar to the secondary market of the stock market. It’s just that exchanges in the currency circle have more power. They have the right to review currency listings and can decide to list or delist currencies.
Of course, if the project team wants to list the currency, it has to pay a huge fee to the exchange for listing the currency. When investors trade in the exchange, they also need to pay handling fees or withdrawal fees. Each exchange has handling fee and withdrawal fee rules. Not all the same. In fact, listing fees, handling fees, and withdrawal fees constitute the profit model of cryptocurrency exchanges. Of course, in addition to these three profit models, the exchange’s profit models also include: “market maker” business to earn price differences, That is, the exchange creates liquidity through continuous buying and selling, acts as a market maker, and earns business spreads at the same time.
Currently, due to the increasingly fierce competition in the industry, listing fees and handling fees will become less and less, or even unnecessary, so regular profits will account for less and less, and other profits will appear. Model, for example: platform currency, leverage fee. Let’s talk about the platform currency first. Platform coins are coins issued by exchanges: OKB and Binance Coin are platform coins. These platform coins issued by exchanges can be exchanged for BTC and ETH. At the same time, the increase in the value of the platform coins themselves can contribute to the development of the exchange.Laying a solid material foundation, for users, holding platform currency can enjoy benefits such as handling fee discounts, platform dividends, and special activities of the exchange. This is the platform currency. The leverage fee is the currency financing function on the platform, which supports margin trading and charges a certain percentage of handling fees to currency financing users.
The above mentioned are actually ecosystems built through the exchange’s own resource output. Now, exchanges are actively deploying the entire industry to obtain income, such as establishing capital, mining pools, wallets, incubators, engineering academies, funds, etc. We believe that if the exchange wants to develop in the long term, it must deploy the entire industry chain, find new hot spots in the industry, and build a complete ecosystem. Therefore, it must increase the proportion of strategic profits.
3. Blockchain Media
In the past two years when blockchain has become popular, not only have there been many project parties, but also media have sprung up like mushrooms after a rain. Currently, there are about 200 well-known blockchain media. Go home. The content on the blockchain media platform probably revolves around the following points: policies, hackers, exchanges, bosses, and project parties. In addition to text, the operation method of blockchain media also includes community activities, such as inviting “big guys” to join the group to share. In this way, high-quality content can be accumulated and some traffic can be earned at the same time.
Why must we mention blockchain media? It’s because there are actually some differences between blockchain media and the media in our impressions. What's the difference? The difference is that there are some interests between the blockchain media and the project parties and exchanges mentioned above. We just said that the project party is like a "producer" and the exchange is like a "sales market". Then, the role played by the media is like an "advertising platform". If a project wants to sell well, it needs publicity and advertising, so blockchain media plays such a role. Therefore, the investors of some blockchain media are now project parties and exchanges.
The recent period has been a bear market, and many blockchain media have laid off large-scale layoffs. The reason is simply a shortage of projects and insufficient funds. Therefore, if blockchain media simply relies on investment from project parties and exchanges, as well as advertising revenue, it is actually far from enough. When the bear market comes and project parties and exchanges are affected, then the media will inevitably face a very serious situation. Brutal winter. Therefore, many blockchain media are now also issuing tokens to project parties (the most typical ones are content communities such as Bihu and Biche, which both belong to a media platform and issue tokens to project parties), or some Blockchain media is doing business such as wallets and selling mining machines and renting computing power.
However, we believe that blockchain media, as a media, still plays a role in guiding public opinion after all. Therefore, it is still necessary to return to the essence and be a place to transmit industry value information, rather than a place to pile up advertisements. Therefore, blockchain media should still keep up with the development of technology to achieve its own survival and development, relying on the advantages of blockchain technology and based on the consensus mechanism in the token system to achieve media success.There may be a certain amount of room for imagination in this aspect regarding the reasonable distribution of business interests.
4. Mining machine manufacturers
Bitcoin mining is ultimately a competition for computing power. Whoever has stronger computing power has a greater chance of mining Bitcoin. Therefore, in the entire business system of the currency circle, mining machine manufacturers are an existence that cannot be ignored. Let’s look at a piece of data and we’ll know: In the blockchain industry on the Hurun Report 2018, the richest person is Mr. Zhan Ketuan, a partner from the mining machine manufacturer Bitmain. In addition, according to the prospectus, Bitmain’s net profit in the first half of the year was US$743 million, an increase of nearly 8 times year-on-year. It once occupied more than 70% of the global Bitcoin mining machine market share and became the leader in the mining machine industry. Not only mining machines, Bitmain still occupies a near-monopoly position in mining pools (that is, a cooperative mining model): as of now, the top six mining pools in the world account for 79.2% of the computing power.
Another company that researches mining machine chips - "Canaan", after inventing China's first Bitcoin mining machine, began to engage in research on chips in the fields of blockchain and artificial intelligence. In just a few years In 2006, it also became an internationally renowned chip company.
In fact, as early as 2012, the United States announced that it would release a butterfly mining machine. However, this matter was later considered by many people to be a scam, because the butterfly mining machine was delayed for several years before being released. In the past few years, It has also made the research and development of mining machines in other countries very frightened, and they are all scrambling for time. In a sense, the butterfly mining machine can be regarded as driving the prosperity of the mining machine industry. So, by 2013, mining machines have entered a season of blooming, and a large number of ASIC mining machines have been proposed: either announced research and development, or announced pre-sale, or in the form of spot goods, appeared: Roast Cat Mining Machine, Pigeon mining machine, TMR mining machine, Biter mining machine, Rand Mining Bureau, Little Bee mining machine, Avalon original factory and various OEMs, Garden mining machine, Smart mining machine, etc... maybe Everyone has never heard of these mining machines, because they are basically dead. The remaining ones, Bitmain, Canaan, and Yibang, have become mining machine giants.
However, as a derivative industry under the prosperity of the cryptocurrency market, the price of mining machines is closely related to the cryptocurrency market: in the bull market, mining machines are often in short supply, and miners pay several times higher prices to buy from "scalpers" It is not uncommon to buy mining machines. At this time, mining machine manufacturers have entered a bonus period. But in a bear market, mining machine manufacturers will also be affected by some adverse effects. Miners' enthusiasm for mining wanes, and some manufacturers have to lower the price of mining machines to recover costs. For example, when Bitcoin plummeted in March this year, a certain model of mining machine sold by Huaqiangbei was sold at a price reduction of 5,000 yuan. The price dropped from about 19,000 yuan per unit to
14,000 yuan.
[Summary]
At this point, we can find that whether it is the project party, the exchange, the media, or the mining machine, it can be said to be a relationship of "one prospers, one loses, and both suffer". In the bull market, project owners have enough money to issue tokens through financing, go to the exchange, the exchange earns currency listing fees and transaction fees, and the increase in token value allows the project party to make another profit, and then find the media to advertise, and the media earns advertising fees, then the currency price will be high, and the miners will be enthusiastic The prices are rising, and mining machines are also selling well. But in the bear market, it is completely the opposite sign. Everyone is facing a cold winter, so this is a relationship of "one prosperes, one loses, and both suffer".
The currency circle is introduced here first, let’s introduce the chain circle next.
Section 2 Chain Circle
Chain circle refers to the circle that focuses on blockchain technology. Compared with the currency circle, the chain circle is quite low-key. However, without the technical support of the chain circle, the currency circle cannot exist. Therefore, the chain circle is often ignored, but in fact it is very important. The implementation of future blockchain scenarios will also rely on the technology of the chain circle as a support.
At present, the Chain Circle project mainly focuses on the aspect of data security in the supply chain. We mentioned at the beginning that Wal-Mart, Mastercard, IBM, and those giant automobile manufacturers are trying to use blockchain technology to solve some industry pain points involving data security, such as: the circulation safety of fresh food, vaccines Security, transaction data security, copyright protection, etc.
In terms of supply chain, the most typical example is the express delivery industry. SF Express is currently trying to use blockchain technology to solve pharmaceutical logistics safety. In addition, Alibaba is actively deploying blockchain in Xiongan New Area; Tencent, Internet, NetEase, and JD.com have developed a number of online games based on blockchain. Although these projects are not yet very mature, they have enriched the blockchain The business model provides some relatively broad imagination space.
When it comes to imagination, for the blockchain community, it actually mainly revolves around the topic of "Blockchain+": Blockchain+Finance, Blockchain+Insurance, Blockchain+Agriculture, Blockchain + entertainment, blockchain + artificial intelligence, blockchain + and any other industry... To put it bluntly, it is the implementation of blockchain scenarios. Turning these imaginations into reality is like spreading the Internet to thousands of households. The same as the household.
[Summary]
Blockchain, the underlying technology, was actually a currency system at first, serving Bitcoin. However, as it develops today, this technology has evolved into an idea of change and innovation. Or methods, these ideas and methods are indeed solutions to some pain points in the current Internet era.

❽ What do we need to know about the currency circle?

If you have just entered the currency circle and are about to buy digital currencies, don’t worry, calm down and take a look. I guess the following content will be helpful to you.

1. What is a digital currency wallet
Many people say that a digital currency wallet is used to store digital currency. Generally speaking, there is no problem with this understanding, but in fact, a digital currency wallet is used to store digital currency. It is not a digital currency, but a tool for holding keys (private keys and public keys). With the keys, you can own the digital goods at the corresponding address.By using the digital currency payment address generated in the wallet, you can accept digital currency transfers from others to you, and you can also transfer the digital currency you own to others. Generally speaking, it can be understood as being used to store and trade digital currencies.

2. The structure of digital currency wallet
1. Address:
The wallet address is a string of characters used to transfer money. The wallet address can be understood as a bank card number. Tell anyone that anyone who knows your wallet address can transfer digital currency to your wallet address. Different digital currency addresses are also different. For example, the addresses of EOS and BTC are different.
2. Private key
The private key is a random number generated by the system through a cryptographic algorithm based on the random factors in the user environment. It can be thought of as a bank card password. For each transaction, the payer must issue a private key and the signature generated by the private key.
3. Public key
The public key is generated from the private key and appears in pairs with the private key. The public key can calculate the address and is mainly used to generate the address.
4. Password
When creating a wallet, you need to set a password. The main uses of the password are: 1. The payment password when transferring money; 2. The password needs to be verified when importing the wallet. Passwords are actively set by users, but are much less secure than private keys. The password mainly plays the role of double protection.
5. Mnemonic phrase
The mnemonic phrase is another form of private key. Its function is equivalent to the private key. The mnemonic phrase is generally composed of 12-15 or more English words. The mnemonic phrase can be used to find the private key and restore the wallet, so the mnemonic phrase is very important. Most wallets will prompt users to back up the mnemonic phrase in order to restore the wallet.

3. Classification of digital currency wallets
Can be roughly divided into two categories, hot wallets (online wallets) and cold wallets (offline wallets)
(1) Hot wallets:
Also known as online wallet, it includes light wallet and heavy wallet (full node wallet). Wallets that need to be connected to the Internet can directly perform transaction operations.
1. Light wallet:
Does not store the complete blockchain, only saves data related to itself. It is small in size and can be run on mobile phones, computers, web pages, etc.
Advantages and disadvantages: Does not occupy memory, supports a variety of digital assets, good user experience, quick to get started with novices, but transaction verification is slightly slow

2. Heavy wallet (full node wallet)
Maintains all blockchain data, is completely decentralized, and synchronizes all data. It has better privacy and can verify the validity of transaction data locally.
The advantages and disadvantages of hot wallets: better privacy and faster verification of information, but data needs to be synchronized before each use, takes up a lot of hard drive space, and does not support multiple digital currency transactions.
(2) Cold wallet:
A cold wallet is a wallet that is not connected to the Internet, also called an offline wallet; such as professional hardware equipment, or writing the private key (mnemonic phrase) on paper.
1. Hardware wallet
Hardware wallet uses professional hardware to store digital currency, and stores the private key of digital assets in a separate chip, which is isolated from the Internet and can be plugged and played.
2. Paper Wallet
Write the private key on paper and store it, then delete it

Advantages and Disadvantages of Cold Wallet: It is relatively safe, but it is very troublesome to create a wallet and make transactions. It is difficult for novices to operate, and wallet prices are relatively expensive, generally ranging from a few thousand to tens of thousands of yuan. If you don’t have a large amount of digital assets, you don’t need to consider it.

4. How to choose a digital currency wallet
Light wallets are simpler and more convenient to use, generally support multiple currencies, and are generally suitable for newbies in the currency circle or for transactions and storage. Not a big user. For example, geekwallet
Hardware wallets are not connected to the Internet and are more secure, but the operations are relatively complex and are generally suitable for users with large transactions and storage volumes.

5. Precautions when using digital currency wallets

1. Keep your password well. Once lost, it cannot be retrieved. However, you can reset your password through a mnemonic phrase (provided you keep the mnemonic phrase safely).
2. Keep the private key well. The owner of the private key is the real owner of Bitcoin.
3. Keep the mnemonic phrase well. Once someone else gets the mnemonic phrase, they can transfer all the blockchain assets in the wallet corresponding to the mnemonic phrase.

❾ What is the currency circle ICO?

The currency circle is about the issuance, trading, speculation and all related activities of digital currency (virtual currency), as well as the participating individual users or institutions. Common digital currencies include Bitcoin, Litecoin, etc. Bitcoin is the most heard of here, and many people usually participate in the buying and selling of Bitcoin. Bitcoin was proposed by Satoshi Nakamoto in 2008, with a total number of only 21 million. Its issuance does not rely on any institution. As Bitcoin continues to be mined, the difficulty of generating Bitcoin will increase in the future, and the cost of obtaining Bitcoin may be higher than the price of Bitcoin itself.
