thank you so much now i have to talk with my dealer :
Dude, as you are new in this please understand that miners cannot be "resold".
All the ASIC companies out there take all the share of the profit (when they don't outright scam you AKA BFL)... unless
BTC doubles its value of course.
An example? $3100 for 1 THs is already out of market as it will never ROI. Current price is around half that amount.
Good luck.
