In that case they would take all the financial risk by buying coins already without having the clients their money.
(Since they cannot accept clients money before the ETF is approved and launched.)
I don't think it's them. They have enough coins themselves too.
I don't think it is a new buyer since he would buy where it is cheapest: bitstamp.
I still think it's someone wanting out of gox. And preferring coins for the moment over directly liquidating at bitstamp.
^^ This.... and I don't blame them
How much longer will people keep exchanging coins for Gox IOU's ?
