Fuck Coinbase those KYC cocksuckers. Froze my BTC and I lost from 17k down to 8k while I was trying to cash out before the bubble popped. I'm never going to use a friggin KYC exchange again, I don't care if I gotta use a Nigerian exchange! 
Didn’t they warn you about requiring KYC?
Nope, just one day I was unable to sell my coins until I gave them my SSN and so forth, I then just waited as this had happened on an exchange once (I can't remember if it was coin base or not) and after a period of time They got the message I'm not paying them fee's anymore and my coins held hostage were released. It just so happens that even though I was able to withdraw my BTC (not convert to fiat as I tried) it was right when the market tanked and I don't find that a coincidence nor amusing. The error they were using was that I was exceeding my limit which was an outright lie and I only found out the real reason when I got a ticket answered finally after watching the bubble pop.
