Take your Bitcoin off exchanges.
Not your keys, not your coins. If your BTC isn't in a wallet controlled by you, it's not yours.
Your money will be used to bail out any bad actors if you leave it in an exchange.
This is similar to the legacy banking system, but the legacy banking system prints money to bail out bad actors and pay you back. There's no printing BTC. Once your coins are gone, you'll never get them back.
You can't trust any large institutions because you never know what they're doing in the background.
