I don't understand the reasoning behind this. Why would I do this?
MtGox has been great for Bitcoin. Why would I punish them by using other exchanges?
In my opinion, this is a stupid stunt. Unless, of course, you work for another exchange and are trying to screw your main competition. Then it's an evil stunt.
If you think it is stupid, then please do not participate.
No, I do not work for another exchange. I just want honest markets.
We shouldn't just assume they are honest, but test them from time to time (Hold them accountable).
If I was mtGox, I would fully embrace and encourage this audit and be glad it was happening.
Sure, they would loose some short-term revenue, but the long term effect would ensure that they remain #1.
