The trend of mining has ended, the hype the chaos of panic buying of hardware slowdown since mid year. So investing into more gpu is a great idea.
Free electricity and low-cost machines are the passive income I'm in.
BITCOIN hardware has increased
over the last 12 months it went from 7-49th which is a 7x growth of mining rigs
march-may showed least growth but june onwards showed the most
last years gen asics can be bought at 3x-4x cheaper than last years prices and gen gen asics are coming out soon so the growth will continue
GPU? dang your about 4 years too late, or found yourself in the wrong category.. maybe you're talking about altcoins
Yeah he's definitely talking about eth mining which really isn't ideal since that is mostly going asic now too, GPUs are nice for mining whatever is hot and selling it for Bitcoin, it's just a bit more working jumping on whats currently hot.
