Coinbase is not to be trusted. As with many other complaints I have seen. They have lost/stolen $190.00 from me, they have no Phone number posted anywhere to contact them, they will not answer to any complains you have from the website, or if they do eventually answer to a problem from the website after several weeks, they will just tell you there is nothing they can do.
I am opening a case with the Better Business Bureau, and any other authority I can contact.
DO NOT USE COINBASE... STAY AWAY!
