These 'potential investors' should research and know the differences between altcoins and bitcoin, centralized exchanges or services and decentralized exchanges, self custody and custodial, etc, if they can understand these differences then they would no longer be jittery about anything, but understand that hacks, breaches, censorship and the rest of them all have to do with centralized services.

Exchanges are not supposed to hold your funds and you are not supposed to hold centralized crypto, if you are rekt through doing that, it is your own error, and if potential investors research well they would know the right thing to do, as long as BTC remains safe, secure and decentralized, there is nothing wrong with the general crypto market, but with some specific centralized crypto and services.
