In saying that the profit ain't too great for hi rollers, their wait time for service is rough at best and of course the dreaded service fee is heavy.  It's still way better than trad markets (even after fiat conversion should you choose)and a roll of the die...I'm bet'in btc will go up so the contract(s) with Hashflare may yield better yet, plus I have never lost a dime yet on the "bagpipes"!  I still don't know why that ain't a big part of their marketing... Shit,  if anyone can bargain and haggle with the Chinese and their own local authorities it'd be those lads for sure..
