I hope this won't happen, I just start mining January 2021 with my new graphic cards, I've not even make half ROI back yet, this will break me if bear market starts this soon, I was expecting something around June or July, though I have free electricity since I'm using green energy but I have my targets
If you bought 3080 for less or equal than 1k or 3060/3070 for less or equal than 800 then you will be fine, people buying 3060/3070 for 1400 usd and 3080 for 1800 usd or 3090 for 3k then they will be hurt pretty bad.
