99 euro, dafuq? 1 btc is 90 euro on gox right now.
Yes, at the moment. We soon see $ 135 on Gox. Thats 101, but I always speculate very conservative, so I sell for 99.5.
That's not the right way to do arbitrage. You should sell immediately at the current gox price (perhaps even lower so you get immediate sales), withdraw the money, and re-fund bitstamp when withdrawal is done. Rinse and Repeat.
Under normal circumstances, you're right. But the circumstances are not normal. For obvious reasons I have to wait for the SEPA withdrawal from Gox for weeks. For the same reasons the price on Gox will not decline. I plot the charts and the order book very accurate. The USD / BTC ratio on Gox is now at about $ 200 and it continues to rise. There may be setbacks from time to time, but the price will continue to rise.
