Its not smart to mine at a near breakeven and sell to pay for electrical and make almost nothing. You should just mine at a slight loss if you believe in the future of ETH or crypto and hold it. This is why many just stop mining then because they never think it will resume and go to ATH again.
I don't recommend this because is uncertain that said coin will have a bullrun again, I mean not only that coin, I mean all cryptocoins, so people should be very careful about holding, digital gov coins are coming and that may as well be the end of cryptocoins in general. I always say wait for coins to crash around 95 to 99% then you buy but that is a huge risk too as I'm betting at some point the market will go up again and then I will cashout later on, profiting from it, I have no idea if it will go up at some point, this mentality in crypto is widely dispersed but one day bitcoin will not grow further anymore or may even die, everything has its limits, my point is, do not hold everything in just one bag. Do not bet on crypto 100%, 20% to 40% is perfectly fine.
Mining at loss is also something I dont recommend too as is better to just buy the coin instead of mining and all have the hassle. Also, only the people who bought gpus at the beginning of this bullrun is winning, any further attempts on buying gpus with 3 to 5x the msrp will end in pain because bear market is really bad, the coin does not go up at all, easier to go 100% lower than 20% higher and even if it goes 20% higher then it goes back 20 to 50% lower later on. ETH is a good example, how many times we have seen eth crashing from 300 usd to 100 usd and vice versa? that happened 5 times from 2018 to 2020.
Also is not easy to time the market, I missed my opportunity to sell eth at 4k as I was betting it would go to 5k then I would sell. ETH may as well go back to 4k and then 5k but I dont believe it will hit higher than 7k this time. I will sell the eth I have left once it hits 5k, that is my target, eth 2.0 is a 5k coin, eth 1.0 is still a 100 usd coin in my view. So if bitcoin hits 79k then maximum eth would get is close to 0.08 btc and then crash back to 0.015 btc, will see, this bullrun is not over yet, bear acting like bulls have just one more chance to take btc up and then crash very hard later on.
