According to the news on March 15, Jiang Zhuoer, the founder of Litecoin Mining Pool, believes that this year's high probability is that the profit of mining machines will exceed the increase of Bitcoin. Due to the shortage of chips, the Bitcoin mining power will increase slightly from 2020 to 2021. If the computing power remains the same, the number of coins that a mining machine digs per day is fixed. The last round of increase was the simultaneous increase of currency price and computing power, so the daily output of a mining machine is relatively stable. However, this round of computing power is not as fast as the price of coins, which leads to a faster increase in the value of bitcoins that can be mined per TiB of computing power. This is also the reason for the sharp increase in the price of this round of mining machines.
