That not true that it a scam. Think about how much increase in the market of several coin price has turn out this year. Look at Zcash. it reach $400 today. It almost at the level Ethereum at. Dash price just incremented all the way up to 200 dollar about 2 days ago. The amount of money you put to invest can earn you back either double or triple the amount within a couple month than a 1 year. It also depend what contract your buying to generate coin. Like me I still buy Bitcoin contract for ZEC. For Dash it too late to invest if you didn't buy it when it was on stock. Once you buy like the 20MH contract for DASH, genesis mining would be making 3x the amount as Bitcoin contract does. Think about it. Using affiliate also increase the earning too but it not that easy now a day.
