I'm still not getting anywhere with them because their phone support isn't allowed to deal with account specific questions and their email support is a joke that sends us in a circle. They have a business name, a business checking account, and an EIN, but we have to go through a literal infinite loop of steps to get them to actually follow the law.  Right now, if we contact Coinbase they tell us to go through GDAX, which has no such application form and instead tries to pull information for personal accounts and their contact pages redirect to a personal account.

Meanwhile, Coinbase is STEALING our mining income. For "security" they DELETED all of our addresses and won't even allow internal transfers anymore, despite having been a customer for more than 3 years with sufficient account activity. Seriously, what kind of idiot decided that keeping all the coin that someone sends to an account with a long established business history is good business?
