Went to GDAX and it says trading not available yet in my area. I withdrew everything to wallets. Don't know if it is a glitch or the way it is for awhile?
It's state-by-state, so without knowing where you reside (or where you logged in from), it's tough to say. Last I checked, GDAX only had money transmitter licenses in 36 states, so they definitely don't serve all states.
They did stop servicing Hawaii around this time last year due to burdensome requirements from the Hawaii Division of Financial Institutions, but I haven't heard of any similar terminations in service since then. I don't see anything on
the Coinbase blog, either. I'm also a US resident -- no issues trading on GDAX here. It might have been a glitch, but if your state isn't listed
here, trading may actually be unavailable.
