only if you love risk and do not care much for the coins you invest
I never understood this yearning to invest into some unknown sites and then go around complaining about getting scammed
if you are looking to invest your coins so they bring you additional revenue , try one of the established casino bankrolls
I suggest crypto-games.net , Bustabit , Bitvest , Yolodice - while this is still a risk , at least you can be sure that you won't get scammed
in the long run you are bound to make profit , bar some unforeseen rampaging lucky whale crushing the bankroll
or you could deposit into freebitcoin and get 3% +- annually  , not much but better than nothing
