I don't recommend using coinable because I had a problem with them and it took almost 8 months to recover my funds. Also it is too risky since you don't own your coins, I mean you don't have control over the private keys, a lot of things can happen. It is better to hold your coins in a wallet of yours where you can control your private keys. Also think that Bitcoin (and crypto in general) is created to have a decentralized method of payment, that you can control and where you can be your own bank. What coinbase does is the same as banks, they own your money. Be safe. thank you for reading me.
