Don't worry about my profit margin. That's not my main concern here. 
(I am pretty sure my price from Gridseed is lower than your price from diginforce, but anyway)

You have been proven by Gridseed that you are not official at all, and their sales director even said you are a scam in helixminer's email, but you still try to claim the official reseller title.  If you are not honest, you will find difficult to sell here.
