Lots of people I have known since I got into crypto, have died.
NONE of them prepaired for it. Their keys and logins were lost.
Their money still sits on an exchange.. where it will be forever lost.

If you value the space. Print paper wallets and secure them.
Keep only what you can loose/trade on an exchange.
Have others in the family who'll know how to deal with it.

If most your crypto is on the exchange, you're doing it wrong.
