Graphics cards that can't be cheap are mainly dug in Ethereum. Now the difficulty of the Ethereum has increased and the number of people has increased. Every day, computing power is increasing. From 5. 1 to 5.9 now, the difficulty has been very high. Income has also dropped from more than one day 100 to more than 90. In 50 days, the output will be reduced by half, and April is an opportunity. A batch of future mining machines will be delivered in April. 1559 London hard fork will be implemented in July. Previously, miners' income was reduced by 20%, and at the same time, the ethereum on the market was deflated. Ethereum 2.0 will also be given priority, so the income will be halved if the difficulty increases, and there will be an increase of 1559. There will be a batch of graphics cards with reduced prices in July, because the full return period of a card will be longer and the risk will increase. Then there is the change from pow to pos in Ethereum 2.0 weeks, and then the graphics card mining machine is replaced by a professional mining machine, which is a disaster. It was expected that it would last about two years, but this time it was mentioned that Ethereum 2.0 was given priority, so the variables were great. Nowadays, people who use high-priced graphics cards to enter the market are fools.

The advantage of Ethereum 2.0 is that the price of coins has risen sharply, leading to deflation. When digging coins, you should pledge them, and every time you explode, you should deduct a part of the ethereum to burn it. But I didn't know what the price was at that time. Some people are optimistic about 30,000 RMB, while others are optimistic about 20,000 RMB. Some people are optimistic about Bitcoin 10 million dollars. Why bitcoin? Because bitcoin goes up, Ethereum goes up and bitcoin goes down.
