I just want to thank everyone for all of your input so far. I still haven't decided yet how I want to store my seed phrase. I bought two Ledger Nano X's but my crypto is still on an exchange. I know that, "If it's not your key, it's not your Bitcoin". Still, I feel safe with it so far because the exchange is insured for up to $250,000. I know. I am being stupid by putting trust in an exchange.
