对于刚入加密货币圈的人来说，比特币减半可能是一个十分陌生的词汇，每隔四年它才会出现一次。
The halving of bitcoin may be a very unfamiliar term for those who have entered the encrypt currency circle, and it will only appear once every four years.
在长达11年的比特币历史中，我们见证了三次比特币减半，最近的一次是在2020年5月12日，而第四次减半预计在2024年，可能会对比特币的价格产生巨大的影响。
In the 11-year history of Bitcoin, we have witnessed three halves of bitcoin, the most recent of which was on 12 May 2020, while the fourth reduction is expected to have a significant impact on the price of bitcoin in 2024.
本文将为你介绍什么是比特币减半以及减半将对加密货币市场造成的影响。
This paper will provide you with an overview of the impact that halving bitcoin and halving will have on the crypto-currency market.
比特币减半（the halvening）是指比特币区块奖励的减半，即给予矿工验证新区块的奖励要比减半前少50%。根据比特币减半计划，每当比特币网络挖出21万个新区块时，即大约四年左右的时间，减半就会发生，这个过程会一直持续到2100万枚比特币全部被开采完为止。
The halving of the bitcoin refers to the halving of the bitcoin block incentive, that is, the 50% less incentive given to miners to certify new blocks than before. Under the Bitcoin half plan, when the Bitcoin network digs out 210,000 new blocks, about four years away, the process will continue until 21 million bitcoins are fully mined.
距离我们最近的一次减半事件，发生在2020年5月，比特币的区块奖励从当时的12.5颗减半到现在的6,25；而下一次减半，预计发生在2024年4月或5月。到时候，比特币的区块奖励将会再从现在的6.25降至3.125。随着时间过去，比特币区块奖励只会不断减半，到最后趋近于零。
Our most recent halving event took place in May 2020, when the Bitcoin block reward was halved from 12.5 at that time to 6,25 now; and the next one is expected to be halved in April or May 2024. By that time, the Bitcoin block reward will fall again from the current 6.25 to 3.125.
这种减半机制是比特币价值主张的核心，降低了新比特币释放到流通中的速度，从而保持比特币的价值。
This halving mechanism is at the heart of the Bitcoin value proposition and reduces the speed at which the new bitcoin is released into circulation, thus preserving the bitcoin value.
由于比特币挖矿算法的设定，为每10分钟寻找一次新区块。随着越来越多矿工加入，要寻找新区块所需的时间就会减少。为了维持10分钟的设定，挖矿难度每两周左右就会重置一次。不过，随着比特币网络的急剧增长，现在定位区块的平均时间，还是一直在10分钟以下（大约9.5分钟）。
As a result of the Bitcoin mining algorithm, new blocks are sought every 10 minutes. As more miners join, the time required to find new blocks will be reduced.
也因此比特币减半可以确保，每个区块可开采的比特币数量会随着时间而减少，这样就可以让比特币更加稀有和保持价值。
Thus, the halving of bitcoins ensures that the number of bitcoins that can be mined per block decreases over time, thus making bitcoins rarer and more valuable.
透过对前几次减半的观察，我们可以看出比特币价格在减半前后的几个月时间里都出现了迅速升值现象。但是每次减半的情况都有所不同，市场对比特币的需求也可能会有很大的波动。
By looking at previous halves, we can see a rapid appreciation of bitcoin prices in the months before and after the halving. But every time the halving is different, and the market demand for bitcoins is likely to fluctuate significantly.
想要深入了解比特币减半是什么，我们应该先明白比特币网络的运作方式。
In order to gain a deeper understanding of what a halving of bitcoin is, we should first understand how the Bitcoin network works.
刚入币圈时，很多人可能不太明白「比特币挖矿」的意思。币圈中所说的「挖矿」和我们平时理解的挖矿有些不同，这个词源于比特币白皮书。在白皮书中，中本聪将在数位世界中透过代码产生新比特币的过程，比喻为从地球上提取黄金的物理工作，因此将此过程称为「挖矿」，而透过挖矿赚取加密货币的人，就被称为「矿工」。
When you enter the currency ring, many people may not understand the meaning of "bitcoin mining." The term "mining" in the ring is somewhat different from what we usually understand, a term derived from the Bitcoin White Paper. In the White Paper, Central Benz will create a new bitcoin in a digital world, using codes as a metaphor for the physical work of extracting gold from the Earth, so that the process is called "mining" and is known as "miners" when people dig for encrypted money.
简单来说，比特币区块链技术就像是纪录交易的帐本，挖矿是让矿工相互竞争去计算这本帐本中的一道数学问题，先成功算出答案就等于挖到了这个区块，这时便可以获得新产生的定额比特币作为区块奖励，但该奖励会随着时间减半。
In short, bitcoin block chain technology is like a book to record transactions, and mining is a mathematical problem that allows miners to compete with each other to calculate the book. A successful calculation of the answer would be to dig up the block, which would then be rewarded with a newly generated flat bitcoin, which would be halved over time.
在2009年比特币最早出现的时候，当时的系统每10分钟会奖励验证成功的矿工50个比特币，但现在每10分钟只能获得6.25个比特币。
When Bitcoin first appeared in 2009, the system at that time rewarded successful miners with 50 bitcoins every 10 minutes, but now only 6.25 bitcoins per 10 minutes.
截止今年，比特币已经发生了三次减半了。这三次减半分别发生在2012年、2016年和2020年，预计下次减半将发生在2024年，届时区块数量将达到74万个，区块奖励则从6.25枚比特币减少至3.125枚比特币。
By this year, Bitcoin has been halved three times. The three halves took place in 2012, 2016 and 2020. The next half is expected to take place in 2024, when the number of blocks will reach 740,000, and the block incentive will be reduced from 6.25 bitcoins to 3.125 bitcoins.
以下为比特币减半的历史进程：
The following is the historical process of halving bitcoin:
- 2009年1月3日，比特币正式启动。这时的区块数量为0，每个区块奖励为50枚新BTC。
- 2012年11月28日，比特币发生第一次减半。这时区块数量为210000，每个区块奖励为25枚新BTC。
- 2016年7月9日，比特币发生第二次减半。这时区块数量为420000，每个区块奖励为12.5枚新BTC。
- 2020年5月12日，比特币发生第三次减半，这也是距今最近的一次减半。其区块数量为630000，每个区块奖励为6.25枚BTC。
而下一次则预计发生在2024 年初，由于比特币网络生成新区块的时间是不固定的（一般是10分钟左右），因此减半的确切时间尚不得而知。
The next time, however, is expected to take place early in 2024, and the exact time of halving the number of new blocks is not known, given that the time of generation of new blocks by the Bitcoin network is irregular (usually around 10 minutes).
这将持续到2140 年左右直到2,100 万枚比特币被开采完。届时，矿工的收入将完全来自网路上的交易费用，而不是直接赚取新开采的比特币。
This will last around 2140 until 21 million bitcoins are mined. By that time, miners will earn their income entirely from online transaction costs, not directly from new mining.

为什么比特币减半十分受到投资者的关注呢？
Why is the halving of Bitcoin highly appreciated by investors?
因为比特币减半后，不仅对比特币的价格有影响，也会影响整个加密货币市场。从过去历史中也可以观察到，每次减半后，比特币的价值都会增加。而比特币也一直都是影响加密货币市场的核心关键，所以每次减半事件也都会导致牛市的到来。
It can also be observed from past history that the value of bitcoins increases every time they are halved. And bitcoins have been at the heart of the influence on crypto-currency markets, so every time they are halved, they also lead to a cow market.
对于整个加密市场而言，比特币往往是市场走势的风向标。当比特币上涨时，大多数主要加密货币通常在相当长的时间内保持上涨，因此如以太坊和莱特币等山寨币与比特币牛市呈正相关关系。用「水涨船高」这个词来形容对山寨币的影响是再贴切不过了，因为在过去每次减半发生之后山寨币均处于牛市。尽管目前全球经济陷入混乱，几乎所有资产都在遭受损失，但比特币所有者可能会再次收获减半事件带来的收益。
For the entire encryption market, bitcoin is often a sign of market trends. When bitcoin rises, most of the major encoded currencies tend to remain up for a considerable period of time, and thus have a positive relationship with the city of Bitcoin.
从历史数据来看，比特币价格确实会因预期减半而上涨，通常是在实际事件发生几个月之后。
Historical data show that bitcoin prices do rise as expected by halving, usually a few months after the actual events.
减半标志着新比特币的生产速度在接近供应极限时再次下降，而随着时间的推移，在需求不变的前提下，比特币增发速度减缓可能有助于推动币价成长。
The halving of the production rate of the new bitcoin marks another decline when it approaches the supply limit, and over time, a slowdown in the growth of the bitcoin may contribute to the growth of the currency, provided that demand remains constant.
实际上我们也可以看到，比特币的价格自2009 年上线以来便稳步上涨，当时该代币的交易价格不到1 美元，到2021 年4 月，一枚比特币的价格超过63,000 美元。
Indeed, as we can see, the price of bitcoin has been rising steadily since it came online in 2009, when it was traded at less than $1, and by April 2021, a bitcoin at more than $63,000.
当区块奖励减半时，一些用户会发现电力和硬件等成本的投入导致挖矿活动不再有利可图，如果同时比特币的价格没有上涨，那么他们可能就会完全停止挖矿。虽然这种情况将会减少参与到比特币网络中的算力，但是区块的开采速度并不会受到影响，这是因为软件会自动调整验证交易的难度以保持稳定的比特币挖矿速度。
When block incentives are halved, some users will find that the input of costs such as electricity and hardware makes mining less profitable, and if the price of bitcoin does not rise at the same time, they will probably stop digging completely. While this will reduce the arithmetic of participating in bitcoin networks, the pace of mining of blocks will not be affected, because software will automatically adjust the difficulty of verifying transactions to maintain a stable bitcoin mining rate.
当2100万枚比特币全部被开采出来后，用户将不再获得基于挖矿的新比特币奖励。然而他们可以继续收取由付款人所支付的交易费用，因为这是作为验证交易所能获得的激励。根据预估，最后一枚新比特币被开采出来的时间为2140年。在那之后比特币将趋向通货紧缩，因为流通中的比特币可能会因用户将比特币发送到无效地址等错误而丢失。
When all of the 21 million bitcoins are mined, the user will no longer receive the new bitcoins based on mining. However, they can continue to charge the transaction costs paid by the payer as an incentive for the certification exchange. According to estimates, the last bitcoins will be mined in 2140. After that, bitcoins will tend to become deflationary, because the bitcoins in circulation may be lost due to errors in sending bitcoins to invalid addresses.
第三次比特币减半发生于2020年5月12日，比特币区块的奖励由12.5枚比特币减少至6.25枚比特币。比特币当日的价格上涨2.9%，收报8821.43美元。在随后的几个月时间里，比特币价格并没有立即大涨。
The third half of the Bitcoins took place on 12 May 2020, and the Bitcoins incentive was reduced from 12.5 to 6.25 bitcoins. Bitcoins increased 2.9 per cent on the same day by $8821.43. Bitcoins prices did not rise immediately in the following months.
这跟2016年减半后的比特币走势相似，当年比特币价格经历了较长一段时间的横盘整理。
This is similar to the trend in bitcoin after halving in 2016, when bitcoin prices went through a long period of rounding.
下一次的比特币减半预期将在2024 年发生，届时，比特币的产量将会减少，奖励从6.25 枚比特币降至3.125 枚比特币。
The next half of the bitcoin is expected to occur in 2024, when the production of bitcoin will be reduced from 6.25 bitcoins to 3.125 bitcoins.
比特币上次减半发生在2020 年5 月，2021 年，比特币价格突破68,000 美元，创下历史新高。2016 年减半时也出现类似的情况，比特币价格在隔年也创下历史新高，但值得注意的是，比特币在两次减半并创下新高后，均出现暴跌。
The last halving of Bitcoin occurred in May 2020, and in 2021, the price of bitcoin passed by $68,000, a historic high. A similar situation occurred when the price of bitcoin was halved in 2016, and the price of bitcoin fell by a historic high in the following year, but it is worth noting that bitcoin fell sharply after two halves and reached a new high.
对此，知名加密货币网红Ben Armstrong（BitBoy）认为，比特币将在2024 年再创历史新高。他预计，在2024 年，比特币将实施第四次挖矿奖励减半，激励币价行情走上高峰，飙到12 万美元。
In response, the well-known Red Ben Armstrong (BitBoy) of the encrypt currency net argues that Bitcoin will reach an all-time high in 2024. He anticipates that by 2024, Bitcoin will have halved its fourth mining incentive, stimulating currency prices to peak at $120,000.
此外，知名加密货币交易所火币共同创办人(co-founder)杜军研判，从过去经验来看，到2024年底或2025年初，比特币将迎来下一波牛市。
In addition, the co-founder (co-founder) of the famous crypto-currency exchange, the Du Army, ruled that, from past experience, by the end of 2024 or the beginning of 2025, Bitcoin would be approaching the next cow market.
分析师Jesse Myers 对比特币未来的价格十分看好。他比特币减半周期的角度分析，指出现在就是买入比特币的最佳时期，目前的价格相对于底部的位置并不远，更重要的是，未来2年的趋势（几乎肯定）将是积极的。
Analyst Jesse Myers has a very good future price. From the perspective of the halving of the Bitcoin cycle, he notes that this is the best time to buy bitcoin, that the current price is not far from the bottom, and, more importantly, that the trend (almost certainly) will be positive over the next two years.
此外，外媒Bitcoin Magazine 和加密货币经纪商BTC Direct 支持的Twiiter 帐号Root 在2 月发推暗示，比特币以往发生减半后都会迎接一轮为期数月的牛市，但上涨至历史高点后就会大跌，直到比特币减半周期达69% 才出现触底讯号，推测比特币已到底部。
In addition, the foreign agent Bitcoin Magazine and the encrypted money broker BTC Direct supported Twiiter account Root in February suggesting that Bitcoin, after halving its share in the past, would welcome a months-long cattle market, but that it would fall off to historical heights until it had reached 69 per cent of its half-time cycle and assumed that Bitcoin was at its end.

Q：比特币减半是什么？
A：比特币减半（或简称「减半」）是指开采出新区块的奖励减半的事件，矿工因挖矿而获得的比特币奖励要比减半前减少50%。根据比特币减半计划，每当比特币网络挖出21万个新区块时，即大约四年左右的时间，减半就会发生，这个过程会一直持续到2100万枚比特币全部被开采完为止。
A: Halve Bitcoin (or "50%") refers to a 50% reduction in incentives to exploit new blocks, with miners receiving a 50% reduction in bitcoin incentives for mining as compared to the pre-50% reduction. Under the Bitcoin Halve scheme, the halving of bitcoin every time that Bitcoin’s network digs out 210,000 new blocks, about four years away, will continue until 21 million bitcoins are fully mined.
Q：下一次比特币减半是什么时候？
A：下一次的比特币减半预计将发生在2024年，届时区块数量将达到74万个，区块奖励则从6.25枚比特币减少至3.125枚比特币。由于比特币网络生成新区块的时间是不固定的（一般是10分钟左右），因此减半的确切时间尚不得而知。
A: The next half of the bitcoin is expected to take place in 2024, when the number of blocks will reach 740,000, and the block incentive will be reduced from 6.25 bitcoins to 3.125 bitcoins. Since the time when the bitcoin network generates a new block is irregular (generally around 10 minutes), the exact time to halve is not known.
Q：比特币现在多少？
A：今日Bitcoin 的即时价格为$27857.51，在过去24 小时涨幅为0.22%。
A: The instant price of Bitcoin today is $27857.51, an increase of 0.22 per cent over the last 24 hours.
Q：比特币全部被挖出来的时间将会是哪一年？
A：比特币的总发行量达到1910万，整个网络的超过90%比特币已经被开采完。截止到2140年，比特币将被全部开采完毕，总额度略低于2100万枚。
A: The total circulation of Bitcoins is 19.1 million, and more than 90% of the entire network has been mined. By 2140, Bitcoins will have been fully mined, amounting to just under 21 million.
Q：如何才能从比特币减半中赚钱？
A：在减半过程中交易比特币的最简单方法是使用差价合约等衍生品，它使您能够在不实际拥有比特币所有权的情况下押注比特币的价格走势。另一种选择是通过交易所直接购买比特币，对此您将需要建立一个交易所账户，您还有责任保护好自己比特币钱包中的比特币。
A: The simplest way to trade bitcoins in the process of halving is to use derivatives such as differential contracts, which enable you to bet on bitcoins price movements without actually owning bitcoins. Another option is to buy bitcoins directly through an exchange, for which you will need to set up an exchange account, and you will also be responsible for protecting the bitcoins in your bitcoins purse.
Q：减半后比特币的价格将会是多少？
Q: What will the price of Bitcoin be by half?
A：许多人猜测比特币的价格将在事件发生前后的几周内上涨。这部分是因为减半预计会引起人们对比特币的更多关注，还有就是它将减少进入流通的新比特币的数量。然而，任何价格的上涨都要取决于比特币在减半期间的需求进展。考虑到比特币在过往的大波动背景，没人可以保证比特币届时一定会升值，甚至是保持稳定。
A: Many suspect that the price of bitcoin will rise in the weeks before and after the events. This is partly because halving is expected to cause more attention to bitcoin, and that it will reduce the number of new bitcoins entering circulation.
