Primecoin is now the 4th coin in the past 12 months that Rhett Creighton and cryptojake have started up or forked , pumped and dumped then abandoned. These guys have no morals and heaps of investors have been burnt in these pump/dumps. See Zclassic , Whalecoin , Bitcoin Private.

You have been warned. Just stick to the top 15 coins/tokens.
