After what happened to FTX, I am sure that more traders or investors care about this. Storing assets in the exchange there is something very bad right now. Even someone who traded daily had to withdraw their money when they finished trading.
I'm pretty sure Investors did not habe BTC in storage with FTX.
Finance has Bitcoin but more for show and/or know how to store those securely.
Crypto is a peer to peers network, at least in most whitepapers. Users need to wise up and leran how to install and use a walletl. Most wallets let you buy Crypto.
