币圈吃客损是什么意思 币圈吃客损违法

『壹』 币圈暴跌众生相,有人一夜负债58万,虚拟货币背后的风险有多大

币圈暴跌众生相,有人一夜负债58万,虚拟货币背后的风险有多大?现在整个虚拟货币已经开始大面积下滑,这是一个非常正常的事情,因为他们背后存在着巨大不确定性。下面给大家具体分析一下,朋友们可以作为一种参考:

第三,由于新冠疫情影响,任何物品都会重新定价,这也影响到虚拟货币:

新冠疫情发生之后,全世界经济体系遭到非常大破坏,从而导致很多物品,需要重新定价。而虚拟化货币,这些年发展太快,所以就需要重新来定价。在这样背景下,自然他们会全面调整,高出预期的价值,自然会导致虚拟货币整体崩盘。这也是虚拟货币,下滑背后重要因素,所以大家一定要躲避风险。

『贰』 最近币圈的暴跌真正的原因是什么

最近,新兴加密货币——狗狗币暴跌的关注度居高不下,在此轮由加密货币“大盘”比特币所引发的暴跌中,狗狗币一路狂泻不止;跌至最低0.4美元一枚,几乎被腰斩。对于这次币圈暴跌的原因,汇查查有一些小见解:

1,对币圈需求减少了。

疫情蔓延趋势之下,世界范围内交易变少,人们变得保守,社会消费总量大幅度减少,这时候用比特币等结算的交易大幅减少,需求减少,价格会跌。

2、价格崩盘风险高。

受资本投机炒作影响,虚拟货币价格大涨大跌,让普通投资者难以预测,非常容易造成爆仓亏损,历史上如比特币等加密货币在峰值突然大跌的情况就出现了十多次。近期狗狗币先疯狂上涨然后暴跌的背后,就是一场以“马斯克”为代表的资本大鳄收割普通投资者的“割韭菜游戏”。

3、虚拟货币没有内在价值,风险非常之高。

虚拟货币本质上不具备货币交易功能,且不受世界上任何国家承认,目前而加密货币的价格大幅攀升,主要是市场炒作引发的投机行为,一旦世界各国明文否认这些不受国家控制的虚拟货币的价值,虚拟货币将瞬时变得一文不值,而广大投资者持有的虚拟货币也将彻底被套牢。

虽然狗狗币目前已经是第四大的加密货币,市值680亿美元;仅次于比特币、以太坊以及币安币。可能是近年以来“金融资产”中涨幅最大的“资产”。但是,让人之所以建立不起信仰的原因是,因为市场当下还没有取得一定的共识,想不明白这个狗狗币在未来的到底会扮演一个什么样的角色。在投资的角度来说,对于这类实用性不高,主要是靠金融属性来讲故事的加密货币,说实话还是挺令人担忧的。

在投资角度而言,加密货币很有前景,但请谨慎投资。对于狗狗币不会去盲从,更不会有信仰;狗狗币就像马斯克说的那样,“它就是个好玩的收藏品”或者“笑话”。

『叁』 火币网交易数字货币如BTC和usdt进行了买卖,收到黑钱20万被冻结。说这个也是犯罪要拘留我怎么办

构成犯罪会拘留,可以申请律师。

在币圈混的人都知道,比特币BTC、泰达币USDT等数字货币交易是有一定法律风险的,稍有不慎,就有可能收到黑钱甚至触犯刑法。要想在币圈吃口安稳饭,就应该懂得如何化解数字货币交易的犯罪风险,否则,可能今天账户被冻结,明天甚至被拘留,不得安心。

随着公安机关对网络黑产犯罪的打击力度的增加,数字货币交易的刑事犯罪风险也是越来越大,这应该引起所有币圈人的重视,只有重视化解数字货币交易的犯罪风险,合法合规,养成良好的操作习惯,才能做到增强匿名性,预防和防范相关的刑事法律风险,才能走得长远,等在前面的,有可能是牢狱之灾。

数字货币犯罪是新型网络犯罪,与传统犯罪不同,很多人对此类犯罪不了解,也不懂得该如何才能争取到最轻的处罚,数字货币犯罪的定罪量刑标准以及如何才能争取到无罪和罪轻的处罚。



相关信息

虚拟货币交易中,如果买家用来购买虚拟货币资金是诈骗、毒品、色情、赌博等违法所得,一旦买家被抓,将虚拟货币的卖家牵扯进来,如果有证据证明卖家明知买家的资金来源违法,警方就有可能以洗钱罪、非法经营罪、掩饰隐瞒犯罪所得罪以及上游犯罪的共同犯罪(包括诈骗罪、开设赌场罪)等名义将数字货币卖家拘留协助调查。

甚至逮捕、公诉、判刑。对于此类刑事风险的化解所有在币圈混的人都应该重视,例如我们处理的烟台李某20余人网络投资诈骗案,诈骗团伙将诈骗来的钱全部在网站上购买了比特币,警方根据投资平台第三方支付的资金流水将比特币卖家以诈骗罪抓获。

『肆』 币圈崩盘,币圈未来会何去何从

币圈崩盘,币圈未来很难恢复到原来火热的场景,进入这个市场炒作的人不会太多,很多加密货币会消失。

加密货币在诞生之后,因为人为的炒作,因此价格一路高涨,尤其是比特币,更是涨到了几万一枚。很多人受到一夜暴富的蛊惑,进入了加密货币炒作市场,购买大量的加密货币,期望自己一夜暴富,但是很多人还没来得及暴富,暴跌先来了,币圈一夜之间损失惨重,很多人爆仓出局,币圈崩盘上了热搜。

比特币为首的加密货币,未来会如何,成为了不少人心头的疑问。

三、加密货币暴跌,市场会逐渐萎缩,未来会有大量的加密货币消失。

加密货币火爆之后,很多人为了赚钱,发行了各种空气币,这些空气币毫无价值,甚至背后连实际项目都没有,因此这类货币,在币圈暴跌的时候,价格一路下跌,甚至有的加密货币已经清零。币圈未来会有很多加密货币消失,人们不会再看到它们的身影。

币圈崩盘,导致人们开始清醒的认识到,币圈不适合投资,未来币圈不会有发展。大家对此有什么其他看法,欢迎留言讨论。

『伍』 疯狂币圈背后:10万瞬间清零,币圈暴跌真正的原因是什么

对于目前的整个虚拟货币市场来说,这时候会出现大规模的暴跌,是因为整个虚拟货币市场出现了一定的问题,而且各国政府对于整个比特币的打击力度也不断加强,所以说对于整个比特币市场来说,它的整体的市场规模在不断缩减,绝大多数的机构投资者都在高位套现离场,所以说对于整个虚拟货币市场来说,它目前注意一个比较低的位置。

更为关键的是,对于各国政府对于比特币的打击力度也是在逐渐增大的,尤其是对于一些发达的经济来说,他们对于比特币的态度是0容忍的,所以说也经过各种各样的政策手段来封闭比特币的交易平台,所以说对于比特币的价格也出现了非常大的下降。

『陆』 币圈集体崩盘,22万人爆仓,这是发生了什么情况

币圈集体崩盘,22万人爆仓,加密货币全线出现恐慌式崩盘。

比特币价格的急剧上升和下跌造成了许多投机者,这进一步增加了比特币的风险。这种价格波动以及比特币价格和价格之间的严重偏差,使比特币持有人在遇到问题时蒙受巨大损失。其次,也会受到政策的影响,中国互联网金融协会,中国银行业协会和中国支付清算协会联合发布了关于防范虚拟货币交易中投机风险的通知。 该公告强调,金融机构,支付机构及其他会员单位不得使用虚拟货币对产品和服务进行定价,不得直接或间接开展与虚拟货币有关的业务。 实际上,许多中央银行以前都收紧了比特币交易。

『柒』 币圈的割韭菜是什么意思怎么做才能不被人家割韭菜

割韭菜的意思就是小白刚开始投资,不太懂涨跌套路,看着涨了很多,就担心再不买就又涨了,就高价买进去,结果,买进去不就就大跌,跌的多了,一看亏了,就又卖到,也就是割肉了,就真实地亏了很多。如何避免当韭菜呢?有3点,第一是学习,只有懂套路了,才能不追涨杀跌,第二,选择好的交易所,例如火币网(huobi点pro),比特兔交易所(bitrabbit点com)等,为啥呢?因为好的交易所有几个特性,首先,好的交易所能为用户着想,不把用户当韭菜割,第二好的交易所风控严格,不会上线空气项目垃圾项目,这就避免了你会卖到归零的币子。 第三点就是指买优质项目的币子。希望采纳。

『捌』 为什么合约带单都喜欢用小平台

跟单合约一般情况下解决没有经验下单难的问题
对于那些自诞生起就怀着“收割”意图的山寨合约交易所,用户的一举一动都在幕后庄家眼里,想赚钱离场几乎没有可能。现在除了头部交易所,新成立的山寨合约交易所,要么打着带单功能的噱头、要么邀请好友有很高的体验金返点,其中有很多坑和套路。
据一个币圈资深人士透露,一个一个真实日活1000用户的小型交易所,只要凭借合约交易手续费,就能赚一个盆满钵满。而吃客损给交易所带来的收入往往是合约手续费收入的4倍。所以,那些野鸡合约交易所最核心的还是利用用户的爆仓失金来盈利。
你可能会问,爆仓不是玩家间的对赌吗?交易所怎么盈利,这里就不得不提到野鸡交易所经常制造极端行情来使用户定点爆仓的手段了。
1、用户自以为是在和对手盘赌,殊不知他的对手盘就是交易所,爆仓价格明明白白的摆在他面前,明明其他交易所没插针到那个价格。但它就是能到,说爆你就爆你。最后用户只能哑巴吃黄连。
2、另一种情况呢,就是针对很多已经习惯设置止损的用户,进行多空双爆,有时候一觉醒来,发现价格没变,价格波动也没那么大,但单子没了,往往就是被交易所这样“安排”止损了。
3、有些交易所会找许多所谓的“带单老师”,前期让你赚点蝇头小利,等到你大额充值,就二话不说用上面价格操纵的方法套路你,而你的爆仓损失,除了交易所拿一大半之外,还有很高的比例留到你带单老师那里,这就是经典的“客损模式”带单。
4、等到很多KOL拉了足够多人,总资金池也足够大的时候,交易所突然维护,停止提现,合约群的客服也退群,最后连“带单老师”也收割。
对于币圈小白来说,希望能通过区块天眼APP上的曝光栏,大家可以识别币圈里的套路、骗局,学会保护自己的财产。

『玖』 币圈门头沟是啥意思

何为“门头沟”?“门头沟”是MT.Gox的中译名,而MT.Gox是位于日本东京的的一家比特币交易所,早在2010年就开始开展比特币交易业务,是最早参与这项业务的平台之一,由于其参与早,竞争对手少,当时一度成为世界上最大的比特币交易所,其交易量更是占据了全球的80%之多,很多中国的比特币用户最早也都在MT.Gox上面做交易,MT.Gox一时风光无限。
2014年2月,MT.Gox在网站页面宣传停止交易并随后申请破产。网上流传一份文件,透露了其倒闭的直接原因:由于受到攻击,总计744000个比特币失窃,而且这一损失竟然多年都未被发现!按照当时的比特币价格,这些失窃的比特币价值约为3.5亿美金,如果以我们现在的比特币价格来看,75万枚比特币价值大约为66亿美金!
无论是什么原因,这744000个比特币却再也不属于“门头沟”的用户们了。让人匪夷所思的是,被盗的币最终落入谁手?真的不能通过区块链追溯交易去向吗?去中心化的技术却败在了中心化的交易所手里。

『一』The currency world plummeted, and everyone was in debt. Some people were in debt of 580,000 overnight. What are the risks behind virtual currencies?

The currency world was plummeting. Some people were in debt of 580,000 overnight. What are the risks behind virtual currencies? How big is it? Now the entire virtual currency has begun to decline on a large scale, which is a very normal thing because there is huge uncertainty behind them. Let me give you a detailed analysis below, which friends can use as a reference:

Third, due to the impact of the new crown epidemic, any item will be repriced, which also affects virtual currency:

After the outbreak of the new crown epidemic, the global economic system has been greatly damaged, resulting in the need to reprice many items. As for virtual currency, it has developed too fast in recent years, so it needs to be repriced. Under such a background, it is natural that they will make a comprehensive adjustment and the value will be higher than expected, which will naturally lead to the overall collapse of the virtual currency. This is also an important factor behind the decline of virtual currency, so everyone must avoid risks.

『二』What is the real reason for the recent plunge in the currency circle

Recently, the emerging cryptocurrency-Dogecoin’s plunge has attracted a lot of attention. In this round of crypto currency In the plummet caused by the currency "big market" Bitcoin, Dogecoin continued to plummet all the way; it fell to a minimum of 0.4 US dollars a piece, and was almost cut in half. As for the reasons for the sharp decline in the currency circle, Huichacha has some insights:

1. The demand for the currency circle has decreased.

Under the spreading trend of the epidemic, there have been fewer transactions around the world, people have become conservative, and total social consumption has decreased significantly. At this time, transactions settled with Bitcoin and others have decreased significantly, demand has decreased, and prices will fall.

2. The risk of price collapse is high.

Affected by capital speculation, virtual currency prices have risen and fallen sharply, making it difficult for ordinary investors to predict and easily causing liquidation losses. Historically, cryptocurrencies such as Bitcoin have suddenly plummeted at their peaks. It happened more than ten times. Behind the recent crazy rise and then plunge of Dogecoin is a "leek-cutting game" in which capital predators represented by "Musk" harvest ordinary investors.

3. Virtual currency has no intrinsic value and the risk is very high.

Virtual currencies essentially do not have currency transaction functions and are not recognized by any country in the world. The current sharp rise in the price of cryptocurrency is mainly due to speculation caused by market speculation. Once countries around the world explicitly deny these The value of virtual currencies that are not controlled by the state will instantly become worthless, and the virtual currencies held by the majority of investors will also be completely locked up.

Although Dogecoin is currently the fourth largest cryptocurrency with a market value of US$68 billion; second only to Bitcoin, Ethereum and Binance Coin. It may be the "asset" with the largest increase among "financial assets" in recent years. However, the reason why people cannot establish faith is because the market has not yet reached a certain consensus, and they cannot figure out what role Dogecoin will play in the future.. From an investment perspective, to be honest, it is quite worrying for this kind of cryptocurrency that is not very practical and mainly relies on financial attributes to tell stories.

From an investment perspective, cryptocurrency is very promising, but please invest with caution. I will not blindly follow Dogecoin, let alone have faith; Dogecoin is just like Musk said, "It is a fun collectible" or "a joke."

『三』 Huobi traded digital currencies such as BTC and USDT, and received 200,000 black money which was frozen. What should I do if they say this is a crime and I will be detained?

If it constitutes a crime, I will be detained. You can apply for a lawyer.

Everyone who is involved in the currency circle knows that digital currency transactions such as Bitcoin BTC and Tether USDT have certain legal risks. If you are not careful, you may receive black money or even Violate criminal law. If you want to have a stable job in the cryptocurrency industry, you should know how to resolve the criminal risks of digital currency transactions. Otherwise, your account may be frozen today or even detained tomorrow, and you will not have peace of mind.

As the public security organs increase their intensity in cracking down on Internet crimes, the criminal risks of digital currency transactions are also increasing. This should attract the attention of all people in the currency circle. Only by paying attention to resolving digital currency The criminal risks of transactions, legality and compliance, and developing good operating habits can enhance anonymity, prevent and guard against related criminal legal risks, and only then can you go ahead in the long run. What awaits you may be jail time.

Digital currency crime is a new type of cybercrime. Different from traditional crimes, many people do not understand this type of crime and do not understand how to obtain the lightest punishment. The standards for conviction and sentencing of digital currency crimes and How can we win innocence and a lighter punishment.

In virtual currency transactions, if the buyer uses Monetary funds are illegal gains from fraud, drugs, pornography, gambling, etc. Once the buyer is caught, the seller of the virtual currency will be involved. If there is evidence that the seller knows that the buyer’s source of funds is illegal, the police may charge him with money laundering, illegal The digital currency seller was detained to assist in the investigation in the name of business crimes, concealment and concealment of criminal proceeds, and common crimes of predicate crimes (including fraud and opening of casinos).

Even arrested, prosecuted and sentenced. Everyone who is involved in the currency circle should pay attention to the resolution of such criminal risks. For example, we handled the online investment fraud case involving more than 20 people named Li from Yantai. The fraud gang used all the defrauded money to buy Bitcoin on the website. According to the police The flow of funds paid by third parties on the investment platform led to the arrest of a Bitcoin seller for fraud.

『四』The currency circle collapses, where will the currency circle go in the future?

The currency circle collapses, and it will be difficult for the currency circle to return to its original hot scene in the future. People who enter this market for speculation will not Too many and a lot of cryptocurrencies will disappear.

After the birth of cryptocurrency, due to artificial hype, the price has been rising.The price has skyrocketed, especially for Bitcoin, which has risen to tens of thousands. Many people were seduced by the idea of ​​getting rich overnight and entered the cryptocurrency speculation market, buying a large amount of cryptocurrency in the hope that they would become rich overnight. However, before many people had time to get rich overnight, the crash came first, and the cryptocurrency industry suffered heavy losses overnight. Many people liquidated their positions and were eliminated, and the collapse of the currency circle became a hot topic.

The future of cryptocurrencies headed by Bitcoin has become a question on many people’s minds.

3. If cryptocurrencies plummet, the market will gradually shrink, and a large number of cryptocurrencies will disappear in the future.

After the popularity of cryptocurrency, many people issued various air coins in order to make money. These air coins were worthless and did not even have actual projects behind them. Therefore, when the currency circle plummeted, the price of this type of currency dropped all the way. , some cryptocurrencies have even been cleared. Many cryptocurrencies will disappear in the currency circle in the future, and people will no longer see them.

The collapse of the currency circle has led people to clearly realize that the currency circle is not suitable for investment and that the currency circle will not develop in the future. If you have any other opinions on this, please leave a message for discussion.

『五』Behind the crazy currency circle: 100,000 was cleared in an instant, what is the real reason for the currency circle’s collapse

For the current entire virtual currency market, this time will appear The large-scale plunge is due to certain problems in the entire virtual currency market, and governments of various countries are increasingly cracking down on Bitcoin as a whole. Therefore, for the entire Bitcoin market, its overall market size is constantly shrinking. , the vast majority of institutional investors are cashing out at high levels, so for the entire virtual currency market, it is currently paying attention to a relatively low position.

What’s more important is that governments around the world are increasingly cracking down on Bitcoin. Especially for some developed economies, they have zero tolerance for Bitcoin. Therefore, various policy measures have been used to close the Bitcoin trading platform, so the price of Bitcoin has also dropped significantly.

『Lu』The currency circle collapsed collectively, 220,000 people liquidated their positions, what happened?

The currency circle collectively collapsed, 220,000 people liquidated their positions, and there was panic across the board in cryptocurrencies. collapse.

The sharp rise and fall of Bitcoin prices has caused many speculators, which further increases the risks of Bitcoin. This price fluctuation and the severe deviation between the price and price of Bitcoin cause Bitcoin holders to suffer huge losses when they encounter problems. Secondly, it will also be affected by policies. The China Internet Finance Association, the China Banking Association and the China Payment and Clearing Association jointly issued a notice on preventing speculative risks in virtual currency transactions. The announcement emphasizes that financial institutions, payment institutions and other member units are not allowed to use virtual currencies to price products and services, and are not allowed to directly or indirectly conduct business related to virtual currencies. In fact, many central banks have tightened Bitcoin trading before.

『淒』 currency circleWhat does cutting leeks mean and how to avoid being cut by others?

The meaning of cutting leeks is that I just started investing and I don’t know much about the ups and downs. When I see the price rises a lot, I worry that I will lose money if I don’t buy it again. If it goes up again, I buy it at a high price. As a result, it falls sharply after I buy it. If it falls too much, I see a loss, so I sell it again, that is, I cut the meat, and I really lose a lot. How to avoid being a leek? There are three points. The first is to learn. Only when you understand the routine can you not chase the rise and kill the fall. Second, choose a good exchange, such as Huobi (huobi dot pro) and BitRabbit Exchange. (bitrabbit.com) Wait, why? Because a good exchange has several characteristics. First, a good exchange considers users and does not treat users like leeks. Second, the best exchanges have strict risk control and do not treat users like leeks. Air project junk projects will be online, which will prevent you from selling zero coins. The third point is to buy coins for high-quality projects. Hope to adopt.

『8』 Why do people like to use small platforms to bring orders?

Documentary contracts generally solve the problem of difficulty in placing orders without experience
For those who have been pregnant since birth For copycat contract exchanges with the intention of "harvesting", every move of the user is in the eyes of the dealer behind the scenes, and it is almost impossible to make money and leave the market. Nowadays, in addition to the leading exchanges, the newly established copycat contract exchanges either use the gimmick of having single functions or invite friends to get high trial gold rebates. There are many pitfalls and routines in them.
According to a senior person in the currency circle, small exchanges with real daily active users of 1,000 can make a lot of money just by relying on contract transaction fees. The income brought to the exchange by customer losses is often four times the contract fee income. Therefore, the core of those pheasant contract exchanges is to make profits by using users’ liquidated funds.
You may ask, isn’t liquidation a bet between players? How exchanges make profits, here we have to mention the method that Pheasant Exchange often creates extreme market conditions to make users liquidate their positions at fixed points.
1. The user thinks he is betting against his opponent, but he does not know that his opponent is the exchange. The liquidation price is clearly placed in front of him, and it is clear that other exchanges have not reached that price. But it can reach you, and it will blow you up if it wants to. In the end, the user can only eat Coptis chinensis dumbly.
2. Another situation is to carry out long and short double explosions for many users who are accustomed to setting stop losses. Sometimes they wake up and find that the price has not changed and the price fluctuations are not that big, but the order is gone. , it is often "arranged" by the exchange to stop losses.
3. Some exchanges will find many so-called "order teachers" to let you make a small profit in the early stage. When you recharge a large amount, they will use the above price manipulation methods to trick you without saying anything, and your In addition to the majority of the liquidation loss taken by the exchange, a high proportion is left to your order-taking teacher. This is the classic "customer loss model" of order-taking.
4. When many KOLs have attracted enough people and the total fund pool is large enough, the exchange suddenly undergoes maintenance and stops withdrawing money.The customer service team also quit the group, and eventually even the "teachers who took orders" were harvested.
For newcomers to the currency circle, I hope that through the exposure bar on the Block Eye APP, everyone can identify the routines and scams in the currency circle and learn to protect their own property.

『九』 What is the meaning of Mentougou in Biquan?

What is "Mentougou"? "Mentougou" is the Chinese translation of MT.Gox, and MT.Gox is a Bitcoin exchange located in Tokyo, Japan. It started Bitcoin trading business as early as 2010 and was one of the earliest platforms to participate in this business. Due to its early participation and few competitors, it became the largest Bitcoin exchange in the world at that time, and its trading volume accounted for 80% of the world's total. Many Chinese Bitcoin users first did business on MT.Gox. Trading, MT.Gox was all the rage for a while.
In February 2014, MT.Gox announced on its website that it would cease trading and subsequently filed for bankruptcy. A document circulated on the Internet revealed the direct reason for its collapse: due to the attack, a total of 744,000 Bitcoins were stolen, and this loss went undetected for many years! According to the price of Bitcoin at that time, the value of these stolen Bitcoins was approximately US$350 million. If we look at our current Bitcoin price, the value of 750,000 Bitcoins is approximately US$6.6 billion!
No matter what the reason is, these 744,000 Bitcoins no longer belong to the users of "Mentougou". What’s incredible is who got the stolen coins in the end? Is it really impossible to trace the whereabouts of transactions through the blockchain? Decentralized technology has been defeated by centralized exchanges.
