(I'm not justifying Celsius, just saying there are plenty of 'bank' like places to store your crypto)
"Grandpa lived through the Great Crypto Frenzy. He lost all his savings in the Coinbase bankruptcy of 2023. Still doesn't trust digital money."
Those regulations simply don't exist (yet) for crypto. They may be coming, but as of right now if you hold crypto in an exchange, it can evaporate if the exchange goes belly up.
Also, good luck finding someone who lived during the Great Depression and carried a bank balance at the time. They’d have to be 100+ years old!
Which crypto exchanges can promise the same? None of them because they're not banks, even if they put up a fancy website that looks awfully bank-like to retail customers.
Why should I take the risk of a company going bankrupt and liquidating my funds when I can keep the money in my house (wallet)?
Obviously handling your own crypto custody in a private wallet means you're taking on a whole different set of risks. But the key feature of deposit insurance is that it mitigates a risk factor that's both 1) opaque to you, and 2) outside your ability to directly influence. And these are properties many crypto-aligned folks care about.
However, you can deposit cash in FDIC insured bank accounts. Question is what's the equivalent of a bank deposit in the crypto world?
And of course, in most places, banks and other institutions are protected with rules about keeping a certain amount of cash on hand and some sort of insurance mandated by the government.
