Ok,they added support of debit cards and so tried to link my card again and got this message "Error: Your verification charge could not be processed".
Called my bank and they say that all the transcations are cancelled because they are "quasi cash" which is not allowed by them.So WTF? Can anyone confirm it or tell me what to do? I've got several another credit cards but all of them are mastercard,so i can't solve this problem.
Obviously it isn't Coinbase. It's your Bank.
What bank do you have? I suggest using another Bank or Credit Union. So far I haven't had a problem using Citi Bank.
