my first purchase was on july 2016 ,since then i kept buying small amounts and summing up the transaction fees minus what i got NET from withdrawals i have recovered so far 12.5% ..since july 2016 !
Indeed, the revenue forecast displayed is a lie because i can show you proofs that in almost 1 year in have recovered 12.5% roi.
Lets do some math, how many years are needed for a 100% roi (transaction fees for deposits included) from sha-256 ?

8 years !!
I doubt hashflare will resist another 7 years with all the mining difficulty. They will shut down contracts with a perfect excuse "NOT PROFITABLE" = scamming people.
The 30k satoshi withdrawal fee is killing any chance to recover some money of the lower investors. The withdrawal fee should be a percentage of the withdraw . Also all the contracts should be based and limited on 200% ROI (most of users have paid very high transaction fees to deposit to hashflare so this percentage should cover the network fees)
So it is not a matter if hashflare is scamming but when will this happen. It's a time bomb.

I strongly recommend hashflare owners to invest some money in real assets if they want to pay all the members' ROI, at least 100%.
I also recoomend to the future members to not buy sha-256 because this is a trap.
