The worst investment that I bad ever made is that of rpx coin which j had bought with the handsome amount of 200$ at the starting of month April and now my investment reduces to 20$ which is 10* below my investment so I believe that investment in RPX coin is bad luck for me . I cannot fault rpx coin as a bad coin because all alter coins has reduce to to bearish market.

But I think my judgement was wrong at that time to invest in rpx coin rather than that if I buy other coin then there will be not too much loss but I should have 100$ in my wallet. so, this was my worst investment in crypto currency market at the bearish time.
