Cryptocurrencies will continue to grow. The problem is that no one knows how much they will grow and when it happens. Therefore now it is very promising to build a mining farms.
Not only cryptocurrencies are growing in price, but also the complexity of the network, to produce this cryptocurrency is becoming more difficult, mining cryptocurrency is still profitable, but will have to constantly increase the technical capacity to be in a good profit.
The complexity of mining this or that coin depends also on the number of mining farms engaged in the extraction of this coin.
Now there are fewer miners. I hope the extraction of coins will go faster.
