Terrible customer service.
Is this all a deliberate tactic so thousands of crypto-currency holders don't move their assets out? What use is an exchange if it's not asset rich?
I don't think that Coinbase would deliberately do that. This kind of negative publicity will effect their business big time. I too hold a coinbase account and few weeks back I transferred a decent amount of bitcoins to my exchange account without any issue. Even though I had to pay an insanely high fees, but the transaction went on smoothly and got confirmed within 20-25 minutes at max. However, I would love if they implement segwit to their network because initially they were positive about segwit and also sent out an official announcement that they will be supporting it. But when it was called off they didn't send any further announcement. Now since we have segwit in place, I think it will be a good idea for them to implement it. They are not scammers but they are slower compared to others.
