Ty for helping.
KYS no problem for me.
Coinbase doesnt have a service to send to another wallet.
Sell is same to send btc to my friend? (e.g.)
I think you mean KYC (Know Your Customer,) which means you have to send them identification documents. Coinbase does indeed allow you to send crypto to outside addresses, I've done so many times. You may be having trouble understanding their user interface, but they do have a good tech support team. Reach out to them if you're having trouble.
If you are in the US, I can also recommend buying crypto using Binance.US. If you're not in the US you can use Binance.com.
