If your looking for a less risky investment then invest on Mining sites , those sites is more likely not a scam . Another is to Invest in new released Doubler Sites that pays hourly since most doubler sites runs only for just 1-2weeks max. Or just try to put your money in gambling sites such as Bitvest where you can invest and play..
i have invested already in one mining site for now everything is good i have invested like 2 btc for mining ethereum so far the profit is very good ...but i am not sure about that coin ...the time will show if the coin is stable i will make a good profit for 1 year the ROI should be like 200-250% ot more i am not sure havent math them but it should be close to this numbers
