① 比特币手续费点差是多少

"点差"∶最小浮动单位，当汇率变化时，点数波动的差值为"点差"。例如美元/日元(USDJPY)由120.00变为121.00时，121.00-120.00=1.00日元，点差为100点。英镑/美元(GBPUSD),由1.0000变为0.9800时，点差为200点(此换算0.0001美元对应点数是1点，这取决于小数点后有几位有效数字）。

国内的交易平台的交易手续费一般是免费的，所以不存在点差的问题。

④ 什么是比特币合约

比特币合约的基础

比特币合约，是指无需实际拥有比特币也可进行交易的合约。它与必须实际持有数字货币才可进行的币币交易有很大不同。

比特币合约使你能够预测比特币的价格走势和对冲风险。这种交易方式，意味着你投资的是价格趋势，而非资产本身。

在交易比特币合约时，你可以决定做空还是做多。选择做多，表明你预计比特币价格将会上涨。另一方面，选择做空表明你预计价格将会下跌。

杠杆交易

可以选择高杠杆率进行交易，是比特币合约的一项特性。使用杠杆, 意味着你在进行合约交易时,不必投入100％的交易金额。相反，你只需要存入初始保证金，而保证金额度仅占合约总价值的一小部分。

杠杆交易让你在风险管理的同时，用少量的资金占有较大敞口。

永续合约

虽然合约有许多不同类型，本文主要关注永续合约。顾名思义，这些合约没有到期日。使用永续合约做多或做空的交易者，可以无限期持有头寸，除非合约爆仓，这意味着他们遭受的亏损不会超过初始保证金。

永续合约中，比特币的定价以特定的指数价格为基础。指数价格基于多个币币交易市场上比特币的平均价格。

比特币合约已成为一种非常流行的交易工具。许多传统投资者尚未准备将资金分配到数字资产上，但仍希望从诱人的价格波动中受益，而合约交易为他们打开了大门。

如要开启比特币合约交易，需要找到提供合约交易的交易所。 AAX平台，在合规和安全的环境中，为你提供比特币合约交易服务。

⑤ 比特币合约交易后正负含手续费吗

人们宣传比特币的时候常常会讲：“可以向各种张三李四免费转账。”其实不一定，有时还是需要手续费的。

2013年，一个比特币的价格为20美元。2017年，转一个比特币要花20美元。
手续费的目的一来为激励矿工不辍挖矿，二来以维护比特币网络安全（维稳费？）。早期矿工的挖矿底薪比较高，每个区块50枚BTC，但是创世块之后每出21万个块（每四年），底薪减半。所有2100万枚比特币都被挖出后，由交易费充当挖矿奖励。

关于减半算法的代码，长这样。

CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
// Force block reward to zero when right shift is undefined.
if (halvings >= 64)
return 0;

CAmount nSubsidy = 50 * COIN;
// Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
nSubsidy >>= halvings;
return nSubsidy;
}
奖励金在2012年当时候从50比特币减半为25比特币，2016年从25比特币减半为12.5b比特币。大概2020年就会再减半为6.25比特币。

那么，怎么确定什么时候需要掏交易费、掏多少合适？

比特币网络规则内置交易费用结构，取决于系统推荐的（标准）客户端。我们拿比特币核心（bitcoin core）打个比方，看看转帐时，需要过哪几道：

1.花哪些币？

客户端首先确定用哪些币来完成支付。

好比， Bob给Alice转了2枚比特币；Rose又给Alice转了3枚比特币，那么两次转账金额会单独地趴在Alice的钱包中，直到被花出去。（注意：两笔转账不会“自动合并”为5BTC）。

那么，经过一阵子，钱包中会积累不同金额的比特币，所以才说，得考虑下用哪些做支付。

可用金额叫做交易的“输入”，最终发送金额（包括退回到钱包的找零）称为“输出”。

2.避免过于零碎的支付

若交易“输出”（包括找零）小于0.01BTC，则收取0.0001BTC的手续费。 “选币”时，算法会尽量避开那些找零金额低于0.01BTC的币。

3.老币、大额交易优先

若发送的比特币金额过小，或币龄过低，则很有可能被收取费用。每笔交易都有优先级，由“输入”的年龄、金额和交易输入数量决定。

具体而言就是，客户端将每一笔输入的金额与该输入在区块中存在的时间相乘，将所有乘法结果相加再除以交易字节大小。

若结果小于0.576，则收取交易费。所以，有一堆零碎且/或很新的“输入”，又不想掏手续费可以这么干，交易里加上一个大额且较老的输入即可。这里边，比较关键的就是这个金额x年龄的平均值。

如果在第3步中某交易本来是收费的，但随着时间流逝，又有新的区块不断产生，那么原先交易中“输入”年龄也随之增长，进一步提升了交易的优先级，因此第3步中产生的费用可能会被免除。

4.“称重”收费（按每千字节收费）

最后，客户端检查交易的字节长度。长度取决于输入和输出的数量，大致可用下列公式计算：

148 * 输入数量 + 34 * 输出数量 + 10

若长度小于10000字节且在第3步中有足够高的优先级，那么这笔交易最终被确认为免费，反之需收费，费用默认为0.0001BTC/千字节（不足1k的按1k计算）。可自行在客户端相关设置中更改交易费数额。低于0.0001BTC的设置不会生效。新费用设置生效后，将覆盖步骤2中的费用，两者不叠加。

接着说几个例子：

1. 过犹不及

说：Alice钱包中趴着两笔“输入”，金额分别为1BTC和2BTC。然后Alice想买杯2.99999BTC的咖啡。这时就不存在选币这一说了，因为有且只有两笔输入，都用上才够咖啡钱，剩下0.00001BTC找零。注意，步骤2提到：若交易“输出”（包括找零）小于0.01BTC，则收取0.0001BTC的手续费。说明，咖啡交易将被征收0.0001BTC的手续费。结果就是交易会失败，因为Alice手里的余额不足。

这就有意思了：Alice手上有3BTC，但是没法买2.99999BTC的咖啡。Alice可以把3BTC全部付给商家以避免手续费（假设第3步的费用为0），但有些商家可能会要求支付准确的金额。

2. 人品爆发

说：Alice人品大爆发，在某赔率64000的赌博游戏中，用0.02BTC拨来1280BTC。网站支付奖金时，自己钱包里并没有可丁可卯的1280BTC，于是只能用各种零碎输入（含找零）来各种凑。

最后，这笔凑出来的奖金大小是51203字节。是这样，交易大小超过10000字节，费用增至0.0005BTC/每千字节（其实早期的交易费用就是0.0005，后来变成0.0001的），那么，这里的手续费就是52*0.0005 = 0.026BTC。比玩家的本儿还高。

当然，还是比PayPal转便宜。

注：使用Paypal手续费为 4.4% + 0.3 USD/每笔。

好比，1280刀转账，1280*4.4% + 0.3 = 56.62 刀

注意：最后缴纳的手续费是0.0286BTC，有可能是因为没有使用（推荐）标准客户端来创建交易，然后这个客户端在计算费用时有点小问题。

这是个真事儿，见：Bitcoin Transaction

3. 机关算尽，不掏钱

有种交易踏在免费的悬崖边上，大小为9999字节，堪称交易费躲闪之王。全部输入中只有一个是1聪（satoshi，即比特币最小单位，0.000 000 01 BTC = 1 satoshi，以致敬比特币创始人Satoshi Nakamoto）；但是有另一个大额输入拉高了优先级，免除交易费用。

必须支付手续费吗？

捎带脚说一句，手续费其实不是强制的。有些矿工并没有很在意这些收费标准，也会把一些没有手续费的交易记录到区块中。使用标准客户端的“原始交易”（raw transactions）界面能创建手续费低于标准费用的交易，而且，还是有可能人品爆发的被矿工打包入块的。

⑥ 比特币合约交易是什么

1、合约的定义
期货合约是买方同意在一段指定时间之后按特定价格接收某种资产，卖方同意在一段指定时间之后按特定价格交付某种资产的协议。
双方同意将来交易时使用的价格称为期货价格。双方将来必须进行交易的指定日期称为结算日或交割日。双方同意交换的资产称为“标的”。
如果投资者通过买入期货合约（即同意在将来日期买入）在市场上取得一个头寸，称多头头寸或在期货上做多。相反，如果投资者取得的头寸是卖出期货合约（即承担将来卖出的合约责任），称空头头寸或在期货上做空。

2、合约的由来
期货合约是指由期货交易所统一制定的、规定在将来某一特定的时间和地点交割一定数量和质量商品的标准化合约。它是期货交易的对象，期货交易参与者正是通过在期货交易所买卖期货合约，转移价格风险，获取风险收益。
期货合约是在现货合同和现货远期合约的基础上发展起来的，但它们最本质的区别在于期货合约条款的标准化。在期货市场交易的期货合约，其标的物的数量、质量等级和交割等级及替代品升贴水标准、交割地点、交割月份等条款都是标准化的，使期货合约具有普遍性特征。
期货合约中，只有期货价格是唯一变量，在交易所以公开竞价方式产生。

3、合约的分类
数字货币合约可分为：交割合约和永续合约。
（1）交割合约：期货交割是指期货合约到期时，交易双方通过该期货合约所载商品所有权的转移，了结到期未平仓合约的过程。
（2）永续合约：是一种近似杠杆现货交易的衍生品，是以BTC、USDT等币种进行结算的数字货币合约产品。投资者可以通过买入做多来获取数字货币价格上涨的收益，或通过卖出做空来获取数字货币价格下跌的收益。
永续合约与传统期货存在一定差异：它没有到期时间，因而对于持仓时间没有任何限制。为了保证跟踪标的价格指数，永续合约通过资金费用的机制来保证其价格紧跟标的资产的价格。

⑦ 比特币交割合约有什么规则需要注意

次周合约、季度合约都会参与结算，结算以后会以结算基准价重新计算盈亏，结算之后就可以转出盈利部分；如果用户在结算之前平仓，那么结算后开仓所需的保证金和已实现盈亏全部可以转出虚拟合约帐户。

⑧ 比特币的合约收益是怎么算的

二十倍满仓合约相当于你用100元买了2000元的比特币，涨十个点你的收入是200元（+100），第二天你的账户是300元，继续满仓20倍再涨十个点，你的收入是600元（+300），以此类推，
但若跌5个点，你的本金就没了俗称爆仓。

⑨ 什么是比特币期货合约

比特币期货合约，通常是以比特币价格指数为标的的标准化合约。

比特币交易所提供的比特币期货通常是以比特币进行交易的。期货是与现货相对的，现货是实实在在可以一手交钱一手交货的商品，而期货其实不是“货”，是承诺未来一个时间交“货”（标的）的约定（合约）—期货合约。

标的：又叫基础资产（underlying asset），解释了买卖什么东西的问题。目前比特币期货标的都是比特币价格指数，并且结算和交割价格的产生方法都以这个指数为基础。

手续费：与股票交易需缴纳印花税、佣金、过户费及其他费用不同，期货交易的费用只有手续费。比特币期货交易手续费有开仓收费和平仓收费两种，即在建立仓位时收取（如OKCoin）和在平仓时收取（如796）。比特币期货手续费一般是合约总价值的0.03%。

保证金：保证金跟另一个概念息息相关—杠杆，一般以杠杆比例来反映收益和风险水平。如796新推的50倍杠杆（即2%保证金），它意味着投资者投入1个比特币就可以购买50个比特币的期货合约（即50倍杠杆）；

或者从另一个角度看，投资者投入的1个比特币相当于购买到的50个比特币的2%（即2%保证金比例）。

通过50倍杠杆，期货相对于现货的收益被放大了50倍，比如同时购买1个币的现货和用1个币买多50个币的期货，假定现货和期货价格都上涨100%，那么现货赚了1个币，而期货则赚了50个币。

(9)比特币合约点差扩展阅读

期货合约是买方同意在一段指定时间之后按特定价格接收某种资产，卖方同意在一段指定时间之后按特定价格交付某种资产的协议。双方同意将来交易时使用的价格称为期货价格。

双方将来必须进行交易的指定日期称为结算日或交割日。双方同意交换的资产称为“标的”。如果投资者通过买入期货合约（即同意在将来日期买入）在市场上取得一个头寸，称多头头寸或在期货上做多。

相反，如果投资者取得的头寸是卖出期货合约（即承担将来卖出的合约责任），称空头头寸或在期货上做空。

① What is the spread of Bitcoin handling fees?

"Spread": the minimum floating unit. When the exchange rate changes, the difference in point fluctuations is the "spread". For example, when USD/JPY (USDJPY) changes from 120.00 to 121.00, 121.00-120.00=1.00 yen, the spread is 100 points. GBP/USD (GBPUSD), when the price changes from 1.0000 to 0.9800, the spread is 200 points (this conversion corresponds to 1 point for 0.0001 US dollars, which depends on how many significant figures there are after the decimal point).

The transaction fees on domestic trading platforms are generally free, so there is no spread problem.

④ What is a Bitcoin contract?

Basics of Bitcoin contracts

Bitcoin contracts refer to contracts that can be traded without actually owning Bitcoin. It is very different from currency-to-crypto trading, which requires physical possession of the digital currency to proceed.

Bitcoin contracts enable you to predict Bitcoin price movements and hedge risks. This type of trading means that you are investing in price trends rather than the asset itself.

When trading Bitcoin contracts, you can decide to go short or long. Choosing to go long indicates that you expect the price of Bitcoin to rise. On the other hand, choosing to go short indicates that you expect the price to fall.

Leverage trading

The ability to trade with high leverage is a feature of Bitcoin contracts. Using leverage means that you do not have to invest 100% of the transaction amount when trading a contract. Instead, you only need to deposit an initial margin, which is only a small percentage of the total contract value.

Leverage trading allows you to use a small amount of capital to occupy a larger exposure while managing risk.

Perpetual Contracts

Although there are many different types of contracts, this article focuses on perpetual contracts. As the name suggests, these contracts have no expiration date. Traders who use perpetual contracts to go long or short can hold their positions indefinitely unless the contract is liquidated, which means they will not suffer losses exceeding their initial margin.

In perpetual contracts, Bitcoin is priced based on a specific index price. The index price is based on the average price of Bitcoin on multiple cryptocurrency exchange markets.

Bitcoin contracts have become a very popular trading tool. Many traditional investors are not yet ready to allocate funds toon digital assets, but still want to benefit from attractive price movements, and contract trading opens the door for them.

If you want to start Bitcoin contract trading, you need to find an exchange that provides contract trading. The AAX platform provides you with Bitcoin contract trading services in a compliant and secure environment.

⑤ Does the positive and negative transaction fee for Bitcoin contracts include handling fees?

When people promote Bitcoin, they often say: "You can transfer funds to various people for free." In fact, this is not necessarily the case. Sometimes a handling fee is required.

In 2013, the price of one Bitcoin was $20. In 2017, it cost $20 to transfer one Bitcoin.
The purpose of the handling fee is firstly to encourage miners to keep mining, and secondly to maintain the security of the Bitcoin network (stability maintenance fee?). The basic mining salary for early miners was relatively high, 50 BTC per block, but after the genesis block, every 210,000 blocks (every four years), the basic salary was halved. After all 21 million Bitcoins are mined, transaction fees serve as mining rewards.

The code for the halving algorithm looks like this.

CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
// Force block reward to zero when right shift is undefined.
if (halvings >= 64)
return 0;

CAmount nSubsidy = 50 * COIN;
// Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
nSubsidy >>= halvings;
return nSubsidy;
}
The reward was halved from 50 Bitcoins in 2012 It is 25 Bitcoins, which was halved from 25 Bitcoins to 12.5b Bitcoins in 2016. It will probably be halved again in 2020 to 6.25 Bitcoins.

So, how to determine when to pay transaction fees and how much to pay?

Within the rules of the Bitcoin networkSet the transaction fee structure, depending on the system recommended (standard) client. Let’s use Bitcoin Core as an analogy to see what steps are required when transferring money:

1. Which coins should be spent?

The client first determines which coins to use to complete the payment.

For example, Bob transfers 2 Bitcoins to Alice; Rose transfers 3 Bitcoins to Alice, then the amounts of the two transfers will be kept in Alice's wallet separately until they are spent. . (Note: The two transfers will not be "automatically combined" into 5BTC).

So, after a while, different amounts of Bitcoin will accumulate in the wallet, so I say, you have to consider which ones to use for payment.

The available amount is called the "input" of the transaction, and the final amount sent (including the change returned to the wallet) is called the "output".

2. Avoid too fragmentary payments

If the transaction “output” (including change) is less than 0.01BTC, a handling fee of 0.0001BTC will be charged. When "selecting coins", the algorithm will try to avoid coins whose change amount is less than 0.01 BTC.

3. Old coins and large-amount transactions are given priority

If the amount of Bitcoin sent is too small, or the currency age is too low, fees are likely to be charged. Each transaction has a priority, determined by the age of the "input", the amount, and the number of transaction inputs.

Specifically, the client multiplies the amount of each input by the time the input exists in the block, adds all the multiplication results and divides them by the transaction byte size.

If the result is less than 0.576, a transaction fee will be charged. Therefore, if you have a bunch of fragmented and/or very new "inputs" and don't want to pay handling fees, you can just add a large and older input to the transaction. Here, the more critical thing is the average amount x age.

If a transaction in step 3 was originally charged, but as time goes by, new blocks continue to be generated, then the "input" age in the original transaction will also increase, and further The transaction's priority is increased so fees incurred in step 3 may be waived.

4. "Weighing" charges (charged per kilobyte)

Finally, the client checks the byte length of the transaction. The length depends on the number of inputs and outputs, and can be roughly calculated by the following formula:

148 * number of inputs + 34 * number of outputs + 10

If the length is less than 10,000 bytes and in If there is a high enough priority in step 3, then the transaction will eventually be confirmed as free, otherwise it will be charged. The default fee is 0.0001BTC/kilobyte (for transactions less than 1k1k calculation). You can change the transaction fee amount by yourself in the relevant settings of the client. Settings below 0.0001BTC will not take effect. After the new fee setting takes effect, it will overwrite the fee in step 2, and the two will not overlap.

Let’s talk about a few examples:

1. Too much is not enough

Say: There are two “inputs” in Alice’s wallet, each with an amount of 1 BTC. and 2BTC. Then Alice wants to buy a cup of coffee for 2.99999 BTC. At this time, there is no such thing as currency selection, because there are only two inputs, and both are used to get enough coffee money, leaving 0.00001 BTC as change. Note that step 2 mentions: If the transaction "output" (including change) is less than 0.01BTC, a handling fee of 0.0001BTC will be charged. Note that coffee transactions will be charged a handling fee of 0.0001 BTC. The result is that the transaction will fail because Alice does not have enough balance.

This is interesting: Alice has 3 BTC, but she cannot buy 2.99999 BTC of coffee. Alice can pay all 3 BTC to the merchant to avoid the handling fee (assuming the fee in step 3 is 0), but some merchants may require the exact amount to be paid.

2. Character explosion

Say: Alice’s character exploded. In a gambling game with odds of 64,000, she allocated 1,280 BTC with 0.02 BTC. When the website paid the bonus, I did not have the 1,280 BTC in my wallet, so I could only use various bits and pieces (including change) to make up for it.

In the end, the size of the bonus was 51203 bytes. That's right, if the transaction size exceeds 10,000 bytes, the fee increases to 0.0005 BTC/per kilobyte (in fact, the early transaction fee was 0.0005, and later became 0.0001), then the handling fee here is 52*0.0005 = 0.026 BTC. Higher than the player's book.

Of course, it is still cheaper than PayPal.

Note: The handling fee for using Paypal is 4.4% + 0.3 USD/per transaction.

For example, for a transfer of 1,280 knives, 1,280*4.4% + 0.3 = 56.62 knives

Note: The final handling fee paid is 0.0286 BTC, which may be because it was not used (recommended ) standard client to create transactions, and then this client has a little problem calculating fees.

This is a real thing, see: Bitcoin Transaction

3. Don’t pay until all the mechanisms are exhausted

There is a kind of transaction that is free On the edge of the cliff,With a size of 9999 bytes, it is the king of transaction fee dodges. Only one of all inputs is 1 satoshi (satoshi, the smallest unit of Bitcoin, 0.000 000 01 BTC = 1 satoshi, in tribute to Satoshi Nakamoto, the founder of Bitcoin); but there is another large input that raises the priority and exempts the transaction cost.

Do I have to pay a handling fee?

As a side note, the handling fee is actually not mandatory. Some miners do not pay much attention to these charging standards and will record some transactions without fees into blocks. Using the "raw transactions" interface of the standard client can create transactions with lower fees than the standard fee, and it is still possible to be included in the block by miners due to bad character.

⑥ What is Bitcoin contract trading?

1. Definition of contract
A futures contract is where the buyer agrees to receive an asset at a specific price after a specified period of time, and the seller agrees An agreement to deliver an asset at a specific price after a specified period of time.
The price that both parties agree to use for future transactions is called the futures price. The specified date on which both parties must enter into a transaction in the future is called the settlement date or delivery date. The asset that both parties agree to exchange is called the “subject.”
If an investor takes a position in the market by purchasing a futures contract (i.e. agreeing to buy at a future date), it is called a long position or going long on futures. On the contrary, if the position taken by the investor is to sell a futures contract (that is, to bear the contractual responsibility to sell in the future), it is called a short position or going short on futures.

2. The origin of the contract
Futures contracts refer to standardized contracts formulated by futures exchanges that stipulate the delivery of a certain quantity and quality of commodities at a specific time and place in the future. It is the object of futures trading. Futures trading participants transfer price risks and obtain risk returns by buying and selling futures contracts on futures exchanges.
Futures contracts are developed on the basis of spot contracts and spot forward contracts, but their most essential difference lies in the standardization of futures contract terms. For futures contracts traded in the futures market, terms such as the quantity, quality grade and delivery grade of the subject matter, as well as premium and discount standards for substitutes, delivery location, delivery month and other terms are all standardized, making futures contracts universal.
In futures contracts, only the futures price is the only variable, which is generated through open bidding on the exchange.

3. Classification of Contracts
Digital currency contracts can be divided into: delivery contracts and perpetual contracts.
(1) Delivery contract: Futures delivery refers to the process in which the parties to the transaction settle the expired open positions through the transfer of ownership of the commodities contained in the futures contract when the futures contract expires.
(2) Perpetual contract: It is a derivative similar to leveraged spot trading. It is based on currencies such as BTC and USDT.A digital currency contract product for settlement. Investors can gain profits from rising digital currency prices by buying long, or gain profits from falling digital currency prices by selling short.
Perpetual contracts are somewhat different from traditional futures: they have no expiration time, so there is no limit on the holding time. In order to ensure tracking of the underlying price index, the perpetual contract uses a funding fee mechanism to ensure that its price closely follows the price of the underlying asset.

⑦ What are the rules of Bitcoin delivery contracts that you need to pay attention to

The next week contract and quarterly contract will participate in settlement. After settlement, the profit and loss will be recalculated based on the settlement base price. After settlement, it can be transferred If the user closes the position before settlement, all the margin required to open the position after settlement and the realized profit and loss can be transferred out of the virtual contract account.

⑧ How is the contract income of Bitcoin calculated?

Twenty times a full contract is equivalent to buying 2,000 yuan of Bitcoin for 100 yuan, which increases your income by ten points. It is 200 yuan (+100). Your account is 300 yuan the next day. If you continue to fill the position 20 times and then increase by ten points, your income will be 600 yuan (+300), and so on.
But if it falls 5 points, your principal is gone, commonly known as liquidation.

⑨ What is a Bitcoin futures contract?

Bitcoin futures contracts are usually standardized contracts based on the Bitcoin price index.

Bitcoin futures offered by Bitcoin exchanges are usually traded in Bitcoin. Futures are opposite to spot goods. Spot goods are real commodities that can be paid and delivered in one hand. Futures are not actually "goods". They are an agreement (contract) that promises to deliver "goods" (subject matter) at a time in the future - a futures contract. .

Object: Also called underlying asset, it explains the question of what to buy and sell. Currently, the underlying targets of Bitcoin futures are the Bitcoin price index, and the settlement and delivery price generation methods are based on this index.

Handling fees: Unlike stock transactions that require stamp duties, commissions, transfer fees and other fees, futures trading only charges handling fees. Bitcoin futures trading fees include opening fees and closing fees, which are charged when a position is established (such as OKCoin) and charged when a position is closed (such as 796). Bitcoin futures handling fees are generally 0.03% of the total contract value.

Margin: Margin is closely related to another concept - leverage, which generally reflects the level of return and risk in terms of leverage ratio. For example, 796’s newly launched 50 times leverage (i.e. 2% margin) means that investors can purchase 50 Bitcoin futures contracts (i.e. 50 times leverage) by investing 1 Bitcoin;

or From another perspective, 1 Bitcoin invested by an investor is equivalent to 2% of the 50 Bitcoins purchased (i.e. 2% margin ratio).

Through 50 times leverage, the income from futures relative to spot is magnified 50 times.For example, if you buy 1 coin in spot and 50 coins in futures with 1 coin at the same time, assuming that the spot and futures prices both increase by 100%, then the spot will earn 1 coin and the futures will earn 50 coins.

(9) Extended reading on Bitcoin contract spreads

< p>

A futures contract is an agreement in which the buyer agrees to receive an asset at a specific price after a specified period of time, and the seller agrees to deliver an asset at a specified price after a specified period of time. The price that both parties agree to use for future transactions is called the futures price.

The specified date on which both parties must conduct transactions in the future is called the settlement date or delivery date. The asset that both parties agree to exchange is called the “subject.” When an investor takes a position in the market by purchasing a futures contract (i.e. agreeing to buy at a future date), it is called a long position or going long on futures.

On the contrary, if the position taken by the investor is to sell a futures contract (that is, to bear the contract responsibility to sell in the future), it is called a short position or shorting on futures.
