Should I sell out all ETH? Or keep ETH on hand and keep mining patiently in order to come across next bull trend?
How many ethereum you have right now?
If you have many ethereum, I suggest you hold that and not sell if the price does not reach more than $2k or on your target sell price.
It is better to use a small ethereum to sell and take your profit than to sell out all ethereum because we do not know when ethereum price will increase.
If you can still profit from the mining, you can continue to mining ethereum and wait for the ethereum price increase and sell it at a high price.
I go against your idea, if he has a lot of ethereum in his wallet, he should soon split up and start converting to fiat according to each milestone eth is hitting because we had an ideal year for crypto, the altcoin's value has almost recovered relative to its peak, we have spent a long time waiting and continue to waste time waiting is not advised, it is unlikely that next year will continue to be another high point. And even if we make this small mistake, our mining is continuing every day, the amount of ETH per month still allows us to sell at another peak, less profitable but this strategy is safe
