Cryptographic Error scares me greatly

“This is an unheard-of risk in the case of, say, the S&P 500, but it is a very real risk in the case of bitcoin if every aspect of the chain isn't managed carefully. The key risk is that the custodial partner (currently Coinbase) mismanages the keys and ultimately cannot spend the bitcoin they bought due to what I'll call "cryptographic error." If you've ever lost a password, you have always had someone to call to reset it.

In bitcoin, you either hold the private keys and can prove it or you can't, and if you can't, you are NOT spending the bitcoin.”
