Bitcoin is undoubtedly one of the most popular investments in recent years, creating countless wealth myths. Compared with legal tender, bitcoin is more special. Perhaps because of this, bitcoin has been highly concerned by the capital market, and has been given ultra-high value.

In addition to trading, bitcoin can also be obtained through "mining". Bitcoin is essentially a virtual currency with encryption characteristics. The so-called mining is the process of obtaining bitcoin by solving the mathematical problems of encryption hash algorithm through computer technology. What's more, the idea of mining with home computers has sprouted.

Not to mention that the computing power of the whole network is as high as 139.61eh/s, can the home computer withstand high load operation? If you use a home computer to mine, how long can you get a bitcoin?

Some netizens have calculated that the average home computer can dig out 0.0018 bitcoin a day. If you want to dig out a whole bitcoin, it will take about 556 days. You know, a bitcoin is worth 220000 yuan now. After paying 556 days, it won't make much money in the end.

So while this sounds like a viable approach, it's only if the home computer is running 24 hours a day, 556 days a day. Even for the professional mining machine, it will take about a year to recover the cost, so it is obviously unrealistic to realize the mining profit through the domestic machine. It is understood that no brand of home computer has such performance strength. Moreover, mining requires relevant equipment to solve the mathematical problems based on hash algorithm, and its computing power is greater than that of ordinary home computers.

In fact, long before the bitcoin fire, some people used their home computers to mine and found a lot of bitcoin. Today, the value of bitcoin is different from what it used to be. The difficulty of mining bitcoin is countless times higher than that in the past, so it is almost impossible to mine bitcoin with a home computer. Therefore, many retail investors will choose the professional mining machine composed of graphics card array to participate in the mining. It is understood that the average calculated power of the professional mining machine is more than 50 times / s, and the power is as high as 3200W.

But even such a professional mining machine, at least need more than 100 days to return. Moreover, the price of professional mining machine is as high as more than 10000 yuan. Obviously, this way of investing in bitcoin is not suitable for ordinary retail investors with a small budget. In addition, even retail investors with sufficient principal can hardly compete with financial institutions that are also involved in the bitcoin industry.
