People with real money would instead wire the funds to Gemini or ItBit or even a terribly managed company like Coinbase.
KISS
For context, I reported couple of bugs to MtGox back in the day, and even MtGox fixed them in under a month which is more than what I can say for Coinbase. I guess this is what happens when Coinbase speed-hired 100 people in one year with no proper team-building exercises.
Correction, there is no support. I have a bit of money permanently locked in a coinbase account because their support does not reply at all.
At some point I will just have to convert it all to BTC and send it elsewhere. Caveat Emptor.
On the account draining -- well, there's a latency in setting up new bank accounts there. So I'm surprised it's that easy to just yank money out.
Although I did notice there's no account verification. For example, on Vanguard or other platforms they do a small deposit of a few cents and ask you to verify the payment amounts, a process which has a latency of a day or two.
Are there any ways to make coinbase safer other than a very secure password?
