Sorry , 2.5 btc included shipping from China to USA , i cannot afford that .

I was a victim from them and lost too much already .

This is 3 set of 1TH/s Bitcoin miners from BlackArrow . ( Total 3TH/s , can up to 3.5TH/S )
included power supply , LCD , same as the one you buy from Blackarrow .
It hosted and mining in China now , 0.7RMB/hour .
The hosting contract being on the end of October , and it's a half year hosting contract.
After you buy , you can choose continue hosting in China (need pay for the electric fees yourself) ,
or you can tell them to disconnect it and send the machines back to you (need pay for the deliver fees yourself),
or you can go to China to pick it up yourself .

All of the above , 3.5 BTC , 3 set of 1TH/s and the contract for hosting .
