Obviously it would be a different story if ETH was at $55 now rather than $550. So if ETH went to $55 it would of obviously been more profitable to mine and sell rather than hold which would of resulted in a huge loss.
It wouldn't, gpu and electricity prices would still be the same, yeah you can buy cheap gpus on ebay but without warranty on bearrun. If both electricity and gpu prices followed the bearrun in the sense of going down drastically then it would be no different than mining on bullrun. Bearrun issue is electricity cost, bullrun issue is gpu price since electricity price remains the same on both bullrun or bearrun.
Anyway you look, the best approach is to buy coins on bearrun or bullrun, my point being, you will have to pay 2 to 3x more the msrp for gpus on bullrun, and if the market crashes, that gpu will lose a lot of value, you see people nowadays paying $1300 for 3080 to earn $2.20 per day, if the bullrun lasts at least 24 months then is worth, but we know it won't.

On bearrun, if you can buy close to the bottom or on bullrun sell close to the top then you are a winner, question is how do you know the bottom or top? people have different theories about the bottom or top. I'm sure this is not the top yet, it will go a long away before the top, reason no significant crash yet, people are not silly like used to be, they know eth has potential to hit 5000 usd next year and btc around 50k, buying eth now and ride the wave can net you 10x, mining will never give that, on the other side, even if eth crashes now, I dont see it going below, 250 ~ 300 usd not now or ever, this is my bet.
Also from what we know $500 eth price could well be the bottom in 2021 ~2022 of a super bullrun to eth $5000 ~ $10.000. So my point is, you will sell now eth $500, then you will see eth going from $500 to 5k ~ 10k then crashing to $500 and then buy it back? see, it makes no sense. I will ride the wave, not sure about you trolls. Well, since btc at $10, i never got it wrong, I hope i will keep getting it right.
Pay attention, bullrun and peak earnings can never be reached with mining, while it reaches the peak, your mining equipment can earn a certain amount and then if the price crashes, that is it, if you buy and sell, you can sell it all at the top and be done with it for the time being, mining is day by day, my point being price climax on bullrun will be for a day at best. I mean if eth hits 10k then will be for a day at best before it crashes, if you hold eth you can get 100% of earnings, with gpus you can earn the price climax during a single day and that is it.
The truth is miners in general are bears, most of them think the price will crash and they have electricity and other bills to pay. Investors don't care about that kind thing, so they hold until they see it reached somewhat their top, reason investors always win and miners always lose, imagine how much money investors made buying coins from miners on bearrun and miners who say they mine and dont sell their eth then how they pay electricity and other bills? if they use money from a different source then why not turn off their gpus and use that money they are paying electricity and other bills to buy coins? see my point, in the end buying coins will always be a better option no matter how you see it.
The only way mining can be a win is if a user buy a single gpu lets say a 3080 msrp price then mine until prices crashes, sell every single payout and in the end that person bought a gpu for himself, not as a business, this is what btc creator envisioned, decentralization based on single entities.
