Good advice sir Metroid, I bought gpus when eth already reached 1k, I guess I was in a dummy mode at the time, my loss haha, I used to own 12 ETH but too blind to see that bull season will eventually return again, I would have earned a lot right now, anyways I have free electricity and if bear market returns isn't it better to just keep mining?
Free electricity means you can cope with the bear market without any problem, remember that as the price starts going down, who will turn off their computers first are the people who pays the most for their electricity or find mining not attractive anymore and then the ones that will survive the bear market are the ones with the cheapest electricity and that fits your case.
The idea now is, sell all your eth as you mine then wait for the bear market and then buy coins, do not buy gpus, trust me even with free electricity buy coins in the bear market is a better return if you look 3 to 5 years down the line, but to be worth, eth price needs to crash a lot to be attractive, around 100 ~ 200 usd, will it crash to 100 ~200 usd, only time will tell.
