the whole point of cryptocurrency is to be decentralized, so I would like to manage a wallet from my computer (ubuntu 20.04) without relying on a provider (e.g. binance).
I would like to use my wallet freely:
selling, buying, trading and cashing out however I want
mining whatever I want whenever I feel like doing it
How would I do that? I'm less of a beginner and I really could use some advice
