一个比特币要挖多久？普通电脑的CPU挖一个比特币要多久？比特币的产生就是通过不断碰撞的哈希值来计算的。通俗的讲就是算出正确答案的次数。一款普通笔记本电脑的cpu，每秒钟大概可以算800多次，一块中端显卡可以算2000多次。具体算法单位可以参照下图。
How long does a bitcoin have to dig? How long does a bitcoin from a common computer's CPU dig a bitcoin? Bitcoin is generated by a continuous collision of Hashi values. The common word is how many answers are given. The cpu of a normal laptop is about 800 times a second, and a mid-point card is about 2,000 times a second.
因为比特币算法的特性。所以相比做复制逻辑运算的cpu，只做简单重复算法的GPU更适合来挖矿。为了表示现在比特币挖矿有多难。我特意借了一块贴吧上网友的显卡来计算下。
Because of the properties of the bitcoin algorithm. So GPUs are better suited to mine than cpus, which reproduces logic calculations, simply repeat algorithms. To show how hard it is to dig for bitcoins now. I specifically borrowed a sticker bar card from a friend on the Internet to calculate.
这是一块七彩虹的GTX 1080TI Neptune 水冷显卡。
It's a seven-year rainbow GTX 1080TI Neptune water cool card.
以上是这款显卡的参数，从参数上来讲。这款显卡已经十分残暴。当然这是一块N卡。从比特币挖矿角度来讲A卡的效果会好一些。不过只是做测试，无所谓了。黑色按钮是一键超频用的，后边的测试都是基于一键超频以后1594/1708MHZ这个频率来做的。
These are the parameters of this card, which, in terms of parameters, is already brutal. This is, of course, an N-card. The effect of A-card is better from the point of view of bitcoin mining. But it's just a test, it doesn't matter. The black buttons are for an ultra-frequency, and the tests on the back are based on the frequencies of 1594/1708 MHz after an ultra-frequency.
测试平台：cpu i7 6700k 16G内存 测的的算力大约是1.8GH/s也就是0.0018TH/S得出收益是每天0.00000021个比特币，这是一个什么概念呢。按目前一个比特币大约7.6万人民币的价格算，这台配置上万的主机每天能挖出价值一分六厘的比特币。
Test platform: cpu i7,6700k 16G has a calculated capacity of about 1.8 GH/s, or 0.0018 TH/S, which yields a return of 0.00000.00021 bitcoins a day. At the current price of about 76,000 yuan in bitcoins, the host, which is equipped with tens of thousands of dollars, will be able to dig up a bitcoins worth six cents a day.
按这个速度来挖，需要1.3万年才能挖出一个比特币……我天。大家还是洗洗睡了吧。
At this rate, it takes 13,000 years to dig up a bitcoin... my God. Let's go to bed.
比特币为什么这么难挖？
Why is Bitcoin so hard to dig?
因为目前的比特币矿场都是用专用的比特币矿机来挖矿。一个蚂蚁s19矿机的110T算力相当于7500块 1080ti显卡算力的N倍，而一个中型矿场就拥有几万上十万这样的矿机。而这些矿场会把矿机算力进行整合然后通过手机分销，普通人的话这样就有可以了！
Because the bitcoin mines are now used as specialized bitcoins for mining. A 110T machine for an ants19 is equivalent to 7,500, 1080 t-card N times the size of a mine, and a medium-sized mine has tens of thousands of such machines. These mines will integrate the miner's arithmetic and distribute it via mobile phones, so that ordinary people can do it!
所以比特币目前的全网算力是惊人的大，很多人觉得打理挖矿的事情很麻烦，其实不是的。只需要跟矿场合作的形式，一部手机就能搞定，毕竟矿场建造起来需要钱，运维需要专业的技术，再加上不能扰民，所以说能免去很多麻烦。了解更多，就能更清楚的认识到比特币挖矿的魅力了。
So Bitcoin's current full-network computing is amazing, and many people think it's troublesome, but it's not. Just working with a mine, a cell phone can do it. After all, the mine needs money, the maintenance needs expertise, and it can't disturb people, so it's a lot of trouble.
