It was already proven when there was a voting poll made by Crypto Tracker Bot that Pchain lead as the top 1 as users choice among its competitors that was included by Quarkchain. Therefore many users love to use Pchain as their token. Also when you take a look at CMC Pchain still gaining even though almost all altcoins (including QKC) now suffering from the downfall of BTC. That is the basis why Pchain is really worth to invest.
