Storing Bitcoin in your own wallet will be much safer than using an exchange wallet. when we have our personal wallets, then we will be much better off sending them to our personal wallet for greater security. On the exchange it is guaranteed, but for long terms, this is not recommended. because after all, keeping it in your own wallet is better, we have a wallet and we can manage it ourselves. It's different when we save it on the exchange, it's like we're just borrowing the wallet.
