How can their price be half of coinbase? Can you even create and account at mt gox to buy? If you can are you able to even send btc to coinbase?
I'm very confused by the difference in price. Is it a mt gox specific issue? Meaning they're probably going to shut down or be blacklisted by users?
Mt Gox runs a shoddy business that's why. It's very possible that Gox could go under. It's also possible a lot of people wont ever get their money and/or coins back.
