Coinbase is an awful company. I signed up for a debit card for some reason, and it immediately became a fraud target. Someone tried to use it at a restaurant in South Africa, a store in Singapore and a mobile provider in Moldova.
The card was obviously compromised, and the only reason I didn’t lose money is that I didn’t make any available. So called, emailed, texted Coinbase on 5 different occasions and they never deactivated the card and didn’t appear to have a procedure to do so.
Not a place I would trust with money.
