First and foremost, this shows why cryptocurrencies were originally developed: To be able to avoid the central issuer risk. If you still have large balances with centralized custodians, get a self-custodial hardware wallet and withdraw your funds as soon as possible.
If you're a trader, it's okay to maintain some balances at exchanges, but if you're a long-term holder, stick to the above advice.
That's fair. But yeah my advice would be you can still trade in a decentralized way with your wallet too for ultimate safety.
However, even trading on decentralized exchanges is associated with risks (mainly smart contract risk).
