if you register on this site during first 3 month you will get 200GH/s for free for 14 days. which gives you 0.0004927 btc in 14 days so you can reinvest and buy almost 100GH/s for one month and keep doing it and find profit. i am just afraid that they will lose value and break down. but anyway because it's free start if many of us will be interested in, company will get popularity and will survive start crisis so everyone will be happy.
and this is my referal link if anyone is interested https://5sMining.com/r/115736
just register, you lose nothing and if something good happens you will get good profit :)
