It's the first time I have sold! So do they really, seriously charge TEN freaking percent to sell? Oh my god that's a lot of money!!!! So if I happen to hit it big and I want to sell $20,000 worth, CB is going to take $2,000? That sounds like highway robbery to me.
I've sold and withdrew from Coinbase a few times, fees are negligible, don't know what you're talking about.
Are you from USA?
Maybe it's you're bank taking the money.
