I invested around 200USD into Conligus, after some time Conligus was bought by Onecoin and they merged together. If I invested 200USD into Bitcoin instead of Onecoin, I would have thousand percents profit, now I don't have anything. 
lol as if you will not sell your coins earlier after having a profit . There is only a little chances that you still have the coins you bought that year if you invest in bitcoin while its lower. So investing in a wrong investment is not the only reasons why you don't have any today . Even you buy bitcoin that year you also sold it that year since the price is difference is big and no one really know that the price of bitcoin may increase of whatbis its price now.
