I understand that everyone here is really pissed because of the current situation, but if someone still wants to invest some BTC in trading I suggest bitcoin-trader, as I wrote several pages before, there were no issues regarding deposits/earnings/withdrawal since the moment they started their work back in November. Support team is very fast in replies also.
If anyone decide to give it a try, I appreciate if you use my referral link:

They are hiding too, you can find not much of a difference with btc arbs,
they just have fb, g+ twatter and thats it... The same puttern is there they are hiding...
Regarding BTC arbs, I think they are sooo gready that they just cant stop, they just dont know where to stop,
thus they are now returning fractions of initial investment and trying to attract more investors.
UPDATE: In case of Bitcoin Trader, I've just found the Local Representatives page,
and there are lot of contact information, one can check if these are real, I'm contacting Kipp Watson (US representative)
