5.69% of ROI for 10 weeks is a good return of investment already, that's around 2% profit per month, with bigger investment, you will feel the profit.
Let's say you invested 5 btc, then you will get at least 0.125 btc per month or equivalent to 1,179 usd per month, that's a good return, right?
It depends actually from the coins invested in and how much bankroll share you have. For example people investing in Doge are losing their money right now after they were in profit, of course this could change at a later stage. BTC and LTC seems quite stable for the first moment but who knows in the future.
