提到比特币减半这个词，相信很多币友并不陌生，毕竟今年五月份就刚是发生过比特币减半，当时可以说是承包了热搜，但对于币圈新手来说，对于比特币减半的了解仅限于此，因此，很多币圈新手对于比特币多久减半一次？就产生了疑问，接下来币圈子小编就来为大家解惑。
Referring to the term “bitcoin” by half, it is believed that many of our friends are not strangers, after all that in May of this year there was just half of the bitcoin, which could be said to have been contracted, but for the newcomers of the ring, the understanding of the half of the bitcoin was limited to that, so how often did many of the newcomers of the coins halve the bitcoin?
比特币网络大约每十分钟产生一个新区块，每次矿工完成一个区块，就能获得一定数量的比特币作为区块奖励，每开采 210000 个区块其奖励减半。因为每开采一个区块时间为10分钟是被限制的，按这个速度算，奖励减半周期为四年，也就是说每隔4年比特币区块奖励减半一次。
The Bitcoin network produces a new block about every 10 minutes, and each miner completes a block and receives a certain amount of bitcoin as a block incentive, which is reduced by half by 210,000 blocks per block. Because the time for each block to be mined is limited by 10 minutes, at this rate the reward is reduced by four years, that is, by half every four years.

比特币减半后会发生什么?
What happens when bitcoin is halved?
1、供应放缓
1. Slow supply
通过算法保持通货紧缩一直是比特币协议设计的一部分。它的建立是为了确保比特币的价值。削减区块奖励并将比特币的最大可能供应量设定在2100万比特币，使比特币具有了一种抗通胀的特性，这与各国央行随意印钞的倾向背道而驰。目前大约有1750万比特币在流通，只有不到350万比特币可供通过挖矿获得。当下一次区块奖励减半发生时，比特币的年通胀率将从目前的3.8%降至1.8%左右。这将是BTC历史上首次跌破黄金供应增长约2% - 3%的历史平均水平。
Deflation through algorithms has always been part of the Bitcoin design. It was created to ensure the value of bitcoin. By reducing block incentives and setting the maximum possible supply of bitcoins at 21 million bitcoins, Bitcoins became an anti-inflationary feature, contrary to the tendency of central banks to print banknotes at will.
通过算法来维持通货紧缩一直是比特币协议设计的一部分。它的创建是为了保证比特币的价值。规定减少区块奖励，同时把比特币的总量控制在2100万比特币，这赋予了比特币一种抗通胀的性质，与各央行随意印钞的倾向不同。目前流通的比特币约1750万枚，可供开采的比特币不足350万枚。下次区块奖励减半可能会使比特币的年通货膨胀率从目前的3.8%降至约1.8%。这将是比特币历史上第一次跌破黄金供应增长约2% - 3%的历史平均水平。
Maintaining deflation through algorithms has been part of the Bitcoin design. It was created to guarantee the value of bitcoins. The provision of block incentives was reduced, while keeping bitcoins in aggregate at 21 million bitcoins, giving Bitcoins an anti-inflationary character, unlike the tendency of central banks to print banknotes at will. About 17.5 million bitcoins are currently in circulation, with less than 3.5 million bitcoins available for mining.
2、价格或将飙升10倍
2. Prices or prices will soar by 10 times
比特币区块奖励第一次减半时，其价格从300元涨到7995元，涨了25倍;第二次减半时，价格从5011元涨到14多万元涨28倍。所以不少人预测2020年5月份比特币第三次减半会引发比特币价格大飙升，至少上涨10倍左右。然而，这些数字并不是那么明确。2012年减半之后，比特币价格上涨了两个月，2016年减半后一个月的时间里，对通货紧缩几乎没有即时反应。这也可能是一些投机者实施的“买谣言，卖新闻”策略导致
By the time the Bitcoin block incentive was halved for the first time, the price rose from $300 to $7995, a 25-fold increase; by the second half, the price rose from $5011 to $140,000, a 28-fold increase. So many people predicted that the third half of Bitcoin in May 2020 would trigger a sharp rise in bitcoin prices, or at least a 10-fold increase. However, these figures are not so clear. After halving the price of Bitcoin in 2012, two months, and one month after halving in 2016, there was little immediate reaction to the deflation. This could also be &ldquao by some speculators; rumours, selling &rdquao;
奖励减半会导致算力下降吗?
Will halving the incentives lead to a decline in arithmetic?
从2009年到2012年，每区块的奖励是50BTC，每日发行约7200个BTC;2012-2016年间，每区块奖励为25BTC，每日发行约3600个BTC;2016到2020年，每区块奖励减少到12.5BTC，也就是当前的奖励，每日发行1800个BTC;2020到2024年，区块奖励继续减半为6.25BTC，日发行900个BTC，如此逐步减半。矿工的BTC奖励每四年要减少一次，如果价格不上涨，就意味着收入要减半。
Between 2009 and 2012, each block was awarded 50 BTC, with about 7,200 BTC per day; between 2012-2016, 25 BTC, with about 3600 BTC per block per day; between 2016 and 2020, each block was awarded reduced to 12.5 BTC, which is the current one, with 1,800 BTC per day; between 2020 and 2024, block incentives continued to be halved by 6.25 BTC, with 900 BTC per day, thereby reducing them by half.
只有价格上涨，才能抵消损失。但价格上涨并非是一定的事情，减半对于挖矿行业来说，是一个关键的节点。如果收入不能维持一定的水平，那么很多中小挖矿者有可能离开矿业。所以，比特币减半也可能会带来挖矿行业的进一步洗牌。
But price increases are not certain, and halving is a key node for the mining industry. If incomes are not maintained at a certain level, many small and medium miners may leave the mining industry.
目前看，比特币哈希率并没有因为之前币价下跌而大幅下跌，在一定幅度的下跌之后，总的趋势还在上涨，目前超过2017年12月价格巅峰时的算力。即使减半效应也不会带来算力的突然下跌。在上两次的减半之后并没出现哈希率突然下跌的情况。
For the time being, the Bitcoin-Hash rate did not fall sharply as a result of the previous fall in currency prices, and after a certain decline, the overall trend continued to rise, now exceeding the arithmetic of December 2017, when prices peaked. Even the effect of halving would not bring about a sudden decline in arithmetic power.
币圈子小编发现，从历史来看，区块奖励减半并没有导致挖矿哈希率的降低。从上两次看，之所以哈希率没有下降，主要源于比特币价格的上涨。这导致矿工并没有对比特币减半作出撤离算力的措施。
The currency circle has found that, historically, the reduction of block incentives by half has not led to a reduction in the Hashi rate. In the last two cases, the reason that the Hashi rate has not declined is mainly because of the increase in bitcoin prices.
总之，比特币每四年都会有一次比特币减半，而每次比特币减半，都会使得比特币矿工挖矿的难度增大，自然也就是导致比特币价格的上涨，所以对于萌新来说，在这样的关键时候，更要保持清醒的头脑，不能意气行事。
In short, bitcoin will be halved once every four years, and every time bitcoin is halved, it will make it more difficult for bitcoin miners to dig, naturally leading to an increase in bitcoin prices.
