It's pretty clear coinbase is a scam. They responded with a robotic message about how my transaction was flagged as high risk, although this apparently happened AFTER they charged my bank account. I have been reading many threads on them and there is a clear theme of shady/fraudulent practices on their part. I made an uninformed decision when using them and hopefully through a combination of patience and threats to report them to regulators i will be refunded. If I were someone thinking of using coinbase for the first time i would take this as a warning not to do business with them. At the least read up on them. im sure whoever is running this scheme is stashing A LOT of dough away for when the shit hits the fan and its time to get out of Dodge.
