Should I sell out all ETH? Or keep ETH on hand and keep mining patiently in order to come across next bull trend?
Are you into short term profits or for long term gain since if you are worried for the dump well maybe it's best for you to sell your mined coins so that you can sleep well while ETH is on bad shape.
But you can hold and forget then aim for long term holding then do it since it's much advisable since remember those people who became rich on crypto are the holders.
I don't do mining but I would take money I invested first then put a mark where I should sell. For me it seems easy but it's easy to speak that only in theory.
