OP, I suggest you not take some strangers words to dictate how you invest your hard-earned money. We're just like you, guessing which coins will pump and try to profit from others' decision.
Anyway, how do you even determine "the most popular coin"? Trending words on social media? Trading volume on exchanges? Hot keywords on coins aggregators? Most of them changes quickly. I remember seeing a coin name listed as the hot topic in one aggregator, but before I can check where to buy them the lists changed already. So it's hard to know what algorithm they use to determine it. I suggest not rely on those kind of indicators to decide your long-term holding. CMIIW.
