After the last halving, miners earned just 50% compared to what they can get before but because of the bull run the loss is compensated more than expected. The value of Bitcoin more than quadrupled after the halving, so we can therefore say that Bitcoin mining is now a very lucrative enterprise. I am hoping this can induce more players in the Bitcoin mining industry, that is away from China so that there would be more democratization here. More players, the better it can be for the stability of the Bitcoin network.
