I don't have any myself, and haven't paid a lot of attention to it really, but at 0.00378 USD the price of potcoin is the lowest I've seen it yet. Good time to buy? or perhaps a sign that it's not really going to go anywhere?
Hard to say if potcoins will do anything. Once the Feds open up banking in this space there may not be much of a need for potcoin currency, IMO. Much like domaining, it's a speculative sit and wait game.
Potcoin has a good community around it, there are a few other coins with the same theme but I think potcoin is the biggest and most active.
Every week there is a news show called "Mad Potcoins" on the World Crypto Network
