比特币是一种数字虚拟货币，由计算机生成的一串串复杂代码组成，新比特币通过预设的程序制造，随着比特币总量的增加，比特币的价格也在时时变化，现在大家对于比特币的基本信息已经掌握的越来越多，但其实比特币的总量是有限的，并不是可以无限增长的，那么，比特币总量是多少呢？比特币总量有限又是什么意思？下面币圈子小编就来给大家全面讲解一番。
Bitcoin is a digital virtual currency made up of a series of complex codes generated by computers. New bitcoin is manufactured through predefined procedures. As the amount of bitcoin increases and the price of bitcoin changes from time to time, basic information about bitcoin is now increasingly available, but the amount of bitcoin is limited and not unlimited.
2009年中本聪挖出第一个区块比特币创世区块开始，每挖出一个区块的矿工，都会获得50个比特币的奖励。可是，中本聪设计的比特币机制规定：每隔210000个区块奖励就会减半。也就是说，从第1个区块到第210000个区块，每个区块的奖励都是50个比特币;从第210001区块到第420000区块，每个区块的奖励则是25个比特币。
In mid-2009, Ben was able to start digging out the first block of Bitcoin, with 50 bitcoins for every miner who digs one block. However, the Bitcoins mechanism, designed by China, provides for a half of every 210,000 blocks. That is, from block 1 to block 210,000, each block is rewarded by 50 bitcoins; from block 21001 to block 420,000, each block is rewarded by 25 bitcoins.
按照每个区块的产出时间为10分钟计算，每210000个区块的产出时间大约是3.99年。即从2009年到2013年，每挖出一个区块，矿工会获得50个比特币;从2013年到2017年，每挖出一个区块，矿工会获得25个比特币;从2017年到2021年，每挖出一个区块，矿工会获得12.5个……如此减半下去，减半约32次之后，约在2140年，挖矿的奖励就会小于0.00000001比特币，甚至接近0比特币。所以约到2140年，所有的比特币就会全部进入市场，比特币发行完毕，总量2100万个。
From 2009 to 2013, the mining union received 50 bitcoins for every block that was dug up; from 2013 to 2017, the mining union received 25 bitcoins for every block that was dug; from 2017 to 2021, the mining union received 12.5 bitcoins for every block that was dug up; and by that time, about 32 times, about 2140, after that, the incentive to dig mines would be less than 0.000001 bitcoins or even close to 0 bitcoins. So, by 2140, all bitcoins would be brought into the market, with a total of 21 million bitcoins distributed.
这2100万个比特币的发行总量是极限值，但这个数字永远也达不到，因为即使挖100万年，也挖不出2100万个比特币，只是会越来越接近这个极限值而已。如果100万年后挖一个区块奖励的比特币价是0点后面100万亿个0.然后是1.也就说明，其价值只相当于一粒沙子。不过，多年后，即使从区块奖励上得到的奖励只是一粒沙子，用户依然可以从转账费用中获得回报，因此仍然会有人挖比特币。
The total distribution of 21 million bitcoins is the limit value, but that figure will never be reached, because, even if one million years were to be dug, 21 million bitcoins could not be dug, but it would be closer and closer. If one million years were to be dug for a block, the price of one trillion bitcoins would be 0, and then 1 would be the equivalent of only one grain of sand. But, after many years, even if the prize from the block was just a grain of sand, the user would still be able to get a return on the transfer fee, and so someone would still dig bitcoins.
截至2017年5月26日1时08分，全球共开采出468093个区块，共挖出了16351162.5个比特币，还有4648837.5比特币没有被挖出。比特币的最大优点就是不会出现通货膨胀，因为比特币供应总量永远都不会超过2100万个。
As at 0108 hours on 26 May 2017, a total of 468093 blocks had been excavated globally, with 1635162.5 bitcoins excavated, while 4648837.5 bitcoins had not been excavated. The greatest advantage of Bitcoins was that there would be no inflation, because the total supply of bitcoins would never exceed 21 million.
按照中本聪的设计，比特币数量每隔四年减半一次。预计到2140年，比特币总量将达到上限2100万个。程序设计既已如此，因此谁也增加不了比特币的供应量。所以说，比特币的总量是恒定的。
The number of bitcoins is reduced by half every four years according to the medium-bone design. By 2140, the total number of bitcoins is expected to reach the upper limit of 21 million. By now, no one can increase the supply of bitcoins. So, the amount of bitcoins is constant.
很多人并没有深刻理解“总量有限”这个概念。
Many do not have a profound understanding of the concept of “total limitation”.
除了比特币，这个世界的东西基本上没有总量有限的。只要人们想要，总可以制造更多，地球上不够，还可以去地外找。
With the exception of Bitcoin, there's basically no limit to the volume of things in the world. There's always more that people can make, there's not enough on Earth, there's more to find.
因此，可以不夸张的说，比特币是人类历史上第一次面对一个真正总量有限的东西。因此，我们对待它的态度，处置它的思路，要发生根本性改变。
So, it's not an exaggeration to say that Bitcoin is the first time in human history that we have faced a truly limited amount of things. So, we have to change our attitude towards it, and we have to deal with it in a fundamental way.
总量有限意味着，任何赚币行为都是零和游戏，你多赚1个，别人就少赚1个。所以：
The limited amount means that any act of earning money is a zero-sum game, and you earn one more, and you earn one less. So:
如果你通过炒期货，赚币了，那么你赚的币，一定是别人亏的;因为不可能人人都能通过炒期货赚币。
If you make money through futures, then the money you earn must have been lost; because it is not possible for everyone to earn money through futures.
如果你通过炒山寨币，赚币了，那么你赚的币，也一定是别人亏的;因为不可能人人都能通过炒山寨赚币。
If you have earned a coin by burning it, then the money you earn must have been lost, because it is not possible for everyone to earn a coin by burning it.
如果你存币得了利息，赚币了，你很高兴。但是，有没有想过它会暴雷?绝对不可能市面上所有的比特币理财都靠谱，因为如果那样的话，比特币总量就不能有限。
You're happy if you save the money for interest and earn the money. But, have you ever thought it'd be a thunderstorm? There's no way all bitcoins on the market are tied up, because then the amount of bitcoins can't be limited.
其它如量化交易或者挖矿赚币，也都是如此，有人赚币，就有人亏币。
This is also true of other transactions, such as quantitative transactions or mining, where some earn money and others lose money.
那么，参与零和游戏，就要想清楚了，自己的优势是什么?凭什么我就能赢别人?
So, if you're in a zero-sum game, think about it. What's your advantage? How can I win someone else?
同时，我们也可以得出结论，不可能会有一个通用的策略，保证大家都赚币。某些策略可以一时赚币，但一旦大家都知道了，或者规模做大了，它就失效了，原因是比特币总量有限，如果人人都赚，或者有人可以大规模赚，那么比特币的总量就会突破2100万，那是不可能的。
At the same time, we can also conclude that there may not be a common strategy to ensure that everyone earns money. Some strategies can make money for a while, but once everyone knows it, or when it's big enough, it fails, because the amount of bitcoins is limited, and if everyone makes it, or someone can make it on a large scale, then the amount of bitcoins is over 21 million, which is impossible.
你在交易所撸羊毛，赚了不少币。你持续撸下去，最后发现交易所倒闭了，你赚的就是个空头支票。
You're making a lot of coins on the exchange. You keep stomping, and you finally find the exchange closed, and you're making an empty check.
你存币在比特币理财，天天赚利息。你很爽，最后发现平台跑路了，你惦记它的利息，它惦记你的本金。
You keep your money in bitcoin, you earn interest every day. You're happy, you finally find the platform running away, you're thinking about its interest, it's thinking about your principal.
还有很多其它的事情，就不一一列举了。
There are many other things that are not always listed.
对于普通人来说，最稳妥最安全的赚币方式实际上是，通过提升场外赚钱能力，然后持续购买比特币。这个方法看起来很笨，也很慢。但有些事情，慢就是快。限定数量体现价值：
For ordinary people, the safest and safest way to earn money is actually, by raising off-site earning capacity and buying bitcoin on a continuous basis. This way looks stupid and slow. But some things, slow and fast.
关于比特币发行总量的计算，币圈子小编就跟大家聊到这里，通过本文介绍可以看到，每10分钟出块一次，四年减半，这些时间数据其实都是表面现象，底层的参数是每隔210000个区块，比特币产量减半，比特币最终发行总量不可能超过2100万个。如果想要了解更多比特币总量相关知识，可以关注币圈子，币圈子小编后期会持续更新比特币总量相关报道！
With regard to the calculation of the total amount of bitcoins issued, the small editor of the currency circle has talked to you here, and it can be seen that the amount of money per ten minutes is reduced by half by four years, which is actually a superficial phenomenon. The bottom parameter is that every 210,000 blocks, the production of bitcoins is reduced by half, and the total amount of bitcoins is unlikely to be released by more than 21 million. If you want to know more about the amount of bitcoins, you can focus on the circle.
