One of my friend was also going to invest in onecoin, but I told him that bitcoin is more better than onecoin and it is enough to invest only in onecoin, and also I suggest some altcoins to him he is now investing in bitcoin, Litecoin and LIR
Well thats good is much better to trade your money than to believe in ponzi scheme atleast if you failed its your own decision,in life many theft want to own your money and promise you a good profit but in reality they will get your money and earn small profit.
