Some of this information is very sensitive and some is useless. E.g. oldest withdrawal in the queue. If you intentionally DDoS the withdrawal queue by doing many small withdrawals instead of one large, you are placed far back in the queue every time a withdrawal is processed. This is only fair. Some of this is very market sensitive. E.g. total deposits. (Which are in many different currencies, btw, not just USD.) They should not publish this, and if they did it would mean instant death as an exchange. Large investors must depend on MtGox not publishing those numbers. MtGox has very a very strict privacy policy as well. It is important to ensure that no private information can leak out. I can't see any other exchanges publish those numbers either.
The only important number to most people is how long they have to wait for their money if they withdraw today, and how the queue is organized. I have provided the know figures in this thread. It is collected from various sources, and I wish MtGox would make similar information available.
I disagree. I do not see anything wrong with aggregate data transparency as other financial institutions do this already. So, what is your logical rationale for instant death an an exchange providing such figures?
If I want to buy 30k BTC, MtGox is the only exchange where i can do that at a reasonable price. I would transfer 5 mill USD to MtGox to make mu purchase. If it became known to other players that someone just transferred 5 mill USD to MtGox, they would make sure to buy first. So MtGox would be useless for this purchase if they were that transparent. I would go to one of the less transparent exchanges (i.e. ANY other excahnge) instead. So would all other large players. MtGox would lose their large players and die in a few days.
