Shitcoins are a scam. Filecoin is nonsense. Don’t know what nexo is and don’t care. All you need to do to determine if something is a scam is to ask one question: can this purported function be achieved without this shitcoin? The answer is always yes. If you get a NO, then you’re just not thinking right. Shitcoins are money grabs at the expense of weak minded or lazy idiots, or other scumbags who wish to enrich themselves while leaving someone to hold their bags.
