the important thing to remember with altcoins and their hype is that as it is the nature of a hype, it can not last forever. so all we can ever see in these hyped up altcoins is a short term pump that only lasts for a short amount of time. then comes the inevitable dump as the hype eventually runs out.
knowing that you could make better plans for your escape out of that hyped (pumped) up coin before they dump on you.
