As I've noted before on HN the entire concept of people being able to manage their own wallets flies against everything we know about people. People forget stuff, make mistakes, and lose things. The margin of error for a wallet is tiny. It's not rare for crypto forums, twitter, etc to prescribe completely ridiculous processes and systems for securing wallets, backing up seed phrases, etc. There's an entire cottage in…
Print your private key on paper and lose it all when your house burns down. vs Give your private key to an exchange, and enrich the shitheads running the exchange when they run away with your money. First option seems preferable. If you're going to lose your money, better for the money to be truly lost than to enrich a thief.
Absolutely no one needs to be putting a private key on paper in their house, that is insanity.

I check my bank account daily for fraudulent transactions; it would behoove anyone storing any sizeable amount of value to check/refresh on that daily, however that looks like for your form of storage.
