This one's true @OP. Even I had been following them as well as their #1 investment BetKing and so far, gained 30% profit over my investment which is quite better than going for trading by yourself with a lot of risks involved. I have also invested some coins in MPAC that was referred to me by my friend and I have made some coins over there too, you can try it out too.
