We saw another bitcoin halving and now we have further less reward for miners. Bitcoin Hashrate is hitting new records every now and then. Bitcoin mining is only for few rich community members who can afford that expensive miners and fuel them with expensive power.
The question which I wanna ask is that whether we have any other good alternative to this or we will continue to move with this centralized mining for rest of our lives.
You are wrong.
Bitcoin mining ⛏ works with any machine if power is cheap.
Bitcoin mining ⛏ does not work with expensive machines using expensive power.
Expensive power = loser.
Cheap power = winner.
Agree that Bitcoin mining can be done on any machine. But an ordinary laptop if run for full month even on cheap electricity can give you almost zero BTC. Lets just accept the fact that Bitcoin is profitable on expensive machine only and we the new comers have to look for alternatives.
