I know that now mining with the help of proof of stake - will gain momentum and become more popular
Of course, with this kind of mining, the resources of the planet are saved, and it is the most ecological. Thus proof of stake will be number one!
Of course, this method of mining has a disadvantage - large investors will be able to purchase many tokens and the rest of the participants will not get anything ...
The advantage of POS is that for a successful attack on the network, you need to own a large number of tokens. In this case, the attacker himself will incur enormous losses, that is, he will play against himself.
On the other hand, such mining stimulates the accumulation of funds and makes it unequal to users with a small number of tokens. As a result, the crypto currency becomes centralized and a group of the richest users dictates their terms.
