I do not have a complete understanding of bitcoin, but I feel that the PoW concept will not do it in the long run, so I need you to explain to me if I'm wrong.
- First of all, all this work force is crazy, one day it is possible that it is totally unprofitable for mining and the only able to lead is a very large society, so that decentralization Is broken (I feel we are close to this situation)
- It is a significant waste of energy, can we sustain this in the long term.
- Does anyone look for another way to create a block? I've heard about proof of stake, but I'm also not convinced (I think it's worse in terms of centralization)
