Coinbase is such a self righteous scam of a company. They took $10k usd from me that I put in to buy BTC at $455 each and today they are at $555. I have no BTC and no money. All I get is constant excuses as to why I haven't been refunded my money and constant delays. To make matters worse the customer service people are about as rude as you can get. I am surprised it is even legal to do what they are doing to me.
Where are you located ? Why not sue them ? If you're very confident that the sources of your income are legit and not black collar stuff like Gambling,hit the nearest cyber crime department.Send their official address a notice.Spreading awareness about how scammy a site is not going to help you refund your $10k.Take an initiative beyond internet.Scenarios like this are giving bitcoin a bad name.
