Ethereum Network Hashrate is currently: 955 TH/s
Etherecum Classic Network Hashrate is currently: 27 TH/s
Currently with 30MH/s you make $1 per GPU per day with ETC. Prior to any power costs.
If all the 955 TH/s switches to ETC, then the hashrate will become ~ 982 TH/s. Which means the difficulty will go up 36x. So basically the profits go down 36 times.
So $1 per day becomes $0.027 per day before any power costs.
Now lets assume that only half the hashrate are GPUs since the ETH ASICs cannot mine ETC. So 955/2=477TH/s. So ETC Network hashrate will become 504TH/s.
So basically instead of $0.027 per day it will be $0.053 per day. You basically need $0.015 kwh power to make nothing. Nobody except maybe in Iraq got 1 cent power.
I dont believe they will move to other coins, I believe most will just turn off their gpus and then resell their gpus while they can get something out of it, because as we know supply will increase a lot either way, intel gpus coming, eth going pos, new gpus from nvidia aka 4xxx series and amd, plus the second hand market plus many miners with outdated gpus not being able to compete in the mining anymore. Only crazy people are buying gpus right now or have been for sometime, also this is not bear market at all, this still bull market, there is that too and this bull market has been going for a long time already and this is dangerous. I do believe manipulators will one more time pump coins before a huge crash, they want to trap new sheeps close to top once again ehhe
