ppl are discounting Intersango being dragged into the Bitcoinica lawsuit somehow. or at least that their owners are going to take a financial hit which could threaten the site. i hope not.
I removed intersango from my arbitrage bot several weeks ago for this very reason. Moved my capital elsewhere. Thinking of doing the same with CampBx because the volume is so low and they dont have any good exchange to exchange fiat transfer options (like say BitInstant). I miss TradeHill. Arbitrage aint what it used to be...but there are still some very good days.
Same here, I used to arbitrage GBP, USD and EUR on Intersango, but have been keeping only a token balance there lately for the same reason. I'll wait for some clarity on how the Bitcoinica fiasco will affect Intersango before I do any more serious trading there.
