I forgot to add about Coinbase....yes it had a downturn after making staggering profits last year. Yes it “could” go belly up though its very very far from doing so and has major financial backing. Yes if it does and you leave a bunch of your crypto on the exchange you could lose it in that case.
Solution? Don’t leave your crypto on the exchange. You shouldn’t be doing that anyway. As the old saying in crypto goes, not your keys, not your coins. That means if you want your coins to be secure hold them yourself in a crypto wallet or even better still in a cold storage wallet like my Nano X Ledger.
Do you have an instructional resource for this, or could you enlighten me offline?
