Coinbase has lately been manipulating how we purchase currencies to THEIR advantage! When I make a deposit to my bank and then try to buy a crypto currency with it, Coinbase will only let me spend a certain amount from my checking account, while letting me spend an unlimited amount with my debit card... WHICH ARE THE SAME FUNDS FROM THE SAME ACCOUNT! Coinbase makes 3 times as much money when we use our debit cards than from our checking accounts and I believe THIS is their reason for doing so. I've contacted them via phone and email MULTIPLE times but get nowhere. I simply get an email back from them saying "Case Closed" with no explanation, nor do they fix the problem! This is serious manipulation and I believe borders on outright FRAUD!
