you should have multiple wallets.
especially if you are at a larger level.
if you have 50 usd worth of btc a paypal wallet is fine as is a coinbase or kraken wallet.
if you have 100,000 or even 10,000 usd hardware wallets like trezor are good.
i have kraken exchange
i have paypal
i have coinbase
and most of my crypto is in two trezor wallets
