Send in an order for 1300 dollars and they cancelled it. Said their software detected "high risk" behavior on my account. What the hell?! What kind of response is that? What does that even mean. They didn't even give me a better response. The just said "we're sorry". If they can't give a better reason, it means they don't have one. They are scamming people selectivity. So I waited 2 weeks and tried again. Same thing. Cancelled automatically by their system. And they kept the fees both times!! If the btc value changes in a way that doesn't benefit them, they blame you saying a Blakeney statement that you are "high risk" they cancel your order, keep your fee, and they aren't losing anything by cancelling the transaction. They are just keeping thousands of people's fees. They don't even have a phone number! Seriously, STAY AWAY FROM COINBASE!!
