try to create a private wallet instead of storing your assets in coinbase, it is very insecure if you store your assets in public services such as coinbase, hacking and closing your account will definitely happen someday
For a good wallet, I think friends have already suggested it to you
it is most convenient for us to store assets in a personal wallet, so that we ourselves are responsible for the security of the assets we have, and even then it should be divided into several wallets to make it even more secure. it is indeed risky if we store assets on the exchange, which we still bear the risk of hacking on the exchange
