It is quite possible that there was quite a bit of money in fiat waiting in the reserves on bitstamp... and that money was NOT newly deposited into bitstamp today.   However, now that there seems to be some quasi-resolution to the GOX situation (which still remains quite unclear), some investors are putting in their buy orders with their fiat and so NOW all that reserve fiat, is suddenly showing up on the books.  I would venture to bet that there is quite a bit more fiat in the reserves waiting for a clearer signal regarding a GOX resolution and to thereafter jump in.  When that GOX resolution comes, we will truly have to da moon momentum.. UNLESS there is some new shenanigans (what could that be? government sabotage of sorts?)
