Yep you guys got it right.It was mybitcoin e-wallet.So no way i can claim and get my coins back?
Currently i have  radeon 5870 card is it worth it to mine with it ? The price is like 250$ per coin but can i make some coins with that card only or the difficulty now is too high and its not worth it?
Thanks

Really ? Isn't there any way to find who stole my coins ?

Hello guys i had wallet with one of the sites that got hacked in 2011 but i don't remember which one and i am trying to recover my coins.
Can i do that ?
This was my wallet address:18hBTMdjb2LA5hYsq96kxozowFJ71SAF2x
http://blockchain.info/address/18hBTMdjb2LA5hYsq96kxozowFJ71SAF2x this is the info  that i got.It looks like some one got my coins and transfered them.
Can you give me some names of the bitcoin wallet services that got hacked in 2011 so i can remember which  one has my coins and message them so i can get my coins back?
I remember it was online wallet with pretty ugly and simple design.

Not only you i have the same issue check this site tghough http://getbitcoinfaucet.blogspot.com/ you can get 0.25 bitcoins for free

So then i will use  2 x 5870 or   gtx570 and 5870 then i hope my PSU will be enough.
My next rig will be high end  Thanks for the posts guys

I plan to sell the GTX570 and buy 3 x RADEON 5870  is my PSU with 700W enough ?
Or it will be better if i keep my gtx570 and buy 2 more RADEONS 5870 ? Is 700w enough for them ?

Someone please ?
