ASIC is starting to circulate widely and the lack of concrete steps of the developers to cope it,
Supply memory chips in the world that are not able to keep up with demand so the price of GPUs and other components is skyrocketing then now there is a type of staking coin and type masternode coin. POW has been abandoned. meaning that GPU, CPU, and ASIC can not be used anymore in the future.
So what do you think about GPU mining in the future?
I think that ASICs are evil, they are obstacle to decentralization, only GPU mining can give true decentralization, but also I can see that all new coins are trying to build their blockchains on POS mining, maybe in future POW mining will go on the second plan, except maybe Bitcoin.
