Few minutes ago somebody bought 250btc on stamp... with 0% fee, it's a perfect time for arbitrage + gox announced today that their bank doubled the limit for SEPA withdraws.
What are you talking about? Gox dropped fees, not Stamp. I can certainly see them in my order book
Yes but maybe he is taking advantage that there are no fees for BTC withdrawal on Bitstamp. So he can send them to Mtgox to sell them.
