MtGox failed because they relied upon the correctness of their own implementation of the bitcoin protocol. This was a huge mistake, one which I am sure will haunt all involved for a long time. Coinbase is making the exact same mistake. They rely on their own implementation of the bitcoin protocol. Their client has been hard forked repeatedly. Some of these incidents were random, but many were forced; not by attackers but by whitehats trying despirately to show them their error. The danger of using their own implementation cannot be overstated. For the love of god move to the reference client.
