Should I sell out all ETH? Or keep ETH on hand and keep mining patiently in order to come across next bull trend?
If you are doing it for extra or side income and not relying on it for expenses then i would suggest to hold for now and also try to find other eth investment avenues like staking and farming.
Try to compare and calculate better yield among all of these and then you can switch to the better one, hope it will help.
