Damn, i get 2300 PPT from signature bounty, and sold all coins for 3$, now 1 PPT cost 25$, Which time I'm convinced that will be better just HOLD all your coins and waiting for Moon.
we will never be able to guess which coins will become popular, so there is some risk in these investments. but if you have different altcoins, it is better to keep everything, on the difference in price you will definitely win
