Why use Coinbase for that purpose? Just use their features instead.
And where did I say dont use Coinbase to exchange? Believe it or not, most of the beginners in crypto use Coinbase to store their crypto-currencies. I personally live in a country where all other features of Coinbase is blocked. I can't trade, can't buy or sell on the platform. The only thing I can do is use their site as a wallet to enjoy free transactions between users. That's it.
If you can use other features, use it. Just dont store coins for a long term. That's my point.
