I mined Ethereum and Bitcoin a long time ago, although they were worth very little at that time... There were also other cryptocurrencies like Litecoin, Zcash, and others, they were worth almost nothing, and so what I wanted to say is, never sell your coins, even if they are meme coins! Because time makes everything more and more expensive, if not today then in 5-10 years, but someday they will bear fruit!!!
