I've been trading crypto with Coinbase for almost a year now and all of the sudden I received a notice to cancel my account. Coinbase is saying I violated terms of use. I've only purchase amd sold my own crypto as investments. What violation could I have made? They won't tell you anything other than that and then they wouldn't allow me to login to collect my funds. It took a tone of work and phone calls just to get in. So disappointed.
