thank for answers,
so if I withdraw to coinbase, i will not be able to send BTC anywhere until I verify my identity with ID?
I confirmed my coinbase account with email and with my phone also, but sending my ID is something I dont want to do...
You can receive and send BTC on Coinbase without ID verification. I'm using Coinbase for several years and they didn't asked me to provide my ID. They will ask for it only if you will try to make fiat withdrawal. But anyway, as others have mentioned some reasons why you shouldn't use Coinbase. It would best to mine more BTC and withdraw to any wallet that you want.
