When you store your crypto on an exchange, you don't hold the private keys. When you hold your crypto in an Ethereum ERC20 compatible wallet where you own the private keys, you have full control over your funds.
In the past, some exchanges have suffered security breaches and other issues. It makes sense not to see an exchange as a wallet to store your crypto, but a place to exchange. We advise being cautious with storing a large amount of your crypto holdings on exchanges.
We also advise using a hardware wallet to store your crypto.
