Whats happening with the PSD coin is pump & dump. There are several groups on telegram, some with 20k+ members that announce to buy a certain coin at a certain time, etc. So the suggestion is for those who want to look deeper into those coins probably good idea to join those groups and you can be ready for the pump and hope you hit! Coins are often repeated in pumps every few days within a couple weeks (or more) time frame period.
