Guys today withdrawal option in bitcoin were removed. I couldnt withdraw anything as there were no option to withdraw in bitcoin.
Anyone else experiencing this?

UPDATE: its back. I dont know whats happening here but it seems these guys are up to something.

Regarding if they are a ponzi: btc-arbs admin was tracked down and now he cant be so sure about his and his family security, if someone else is risking to get into this position let them. It will be even easier to track down Bitcoin-trader.
