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.
How do you know these things? I had never heard about Rhett Creighton. And how would one mane be able to do the same game with different games he is not the dev of?
Each of the 3 coins I mentioned above have threads on this forum. Go to each thread and read the last 10-20 pages to see ..... You need to do your own due diligence........
