So pity to know that HashFlare.io are cheaters 
28 november 2015 I invested 4000$
12 march 2016 I have only 1,715 BTC or 682$ or 17% of 100% (minus -83% percent on my balance)
Service amount is about 60-70% . You can forgot about your profit. But you can not forgive this cheat.
I prognose to have 15-20% before July comes. Than service amount will up to 100% & it will be end of game.
For that moment I can have 1700$ from all my 4000$... so I will lose 2300$...
No one can have a little profit on this "cloud mining"...
People must know it!

Perhaps you should have make your own maths even before buying cloud mining services with Hahsflare, Genesis-Mining etc... Buying a couple of TH/s is not enough to ROI. I re-quote & correct your statement: No one can have a little profit on any "cloud mining"... With the current level of difficulties, hoping to ROI is foolish.
