Coinbase has the worst customer service of any company in the world.
There are 6200 customers who are using Coinbase with our mining pool who are in limbo because Coinbase has not replied to four times we have tried to contact them over the course of 34 days. This level of service is unacceptable. The customer service is so bad that criminals have taken over their Reddit forums and are now impersonating Coinbase staff, "helping" desperate people get support. They post a number to call and then try to get the user to install executable files that allow them to steal money from Coinbase! If Coinbase actually replied to its tickets, nobody would trust these criminals.
Avoid Coinbase at all costs. bitFlyer is a much more reputable exchange, and every ticket I have ever submitted to them has been answered within three hours.
Bottom Line: No, I would not recommend this to a friend
