Here is a thread on it. --- > http://www.reddit.com/r/Bitcoin/comments/1uhc58/is_huobis_volume_real/
In addition, all of the transactions are supposedly going through the personal bank account of the owner to skirt the Chinese regulations on fiat exchange. If that were the real volume I don't see how that could be managed.
Only deposits and withdrawals go trough his bank account.
All trading (USD/BTC) is virtual until it is actually withdrawn, in fact this opens the possibility of fractional reserve banking (the Sum of everybody's BTC exchange account could be higher than the total amount the exchange actually has).
Right but assuming they are reporting true volume there would still be an unbelievable amount of fiat channelled through this one account. In addition, the no fee policy leaves the door wide open for manipulation by bots.
