Coinbase has a lot of issues - they need to raise more VC and hire some support temps to get through the current shitstorm.
My biggest issue with Coinbase is that they claim insured wallets, but actually only insure the 2% of bitcoins stored in their hot wallets. Cold storage is uninsured. If their cold storage gets lost/stolen/hacked, all holders are going to lose 98% of bitcoins. That's not insurance.
