I will join for sure.

My largest worry is that the largest group that is following Nyan Cat is the younger people,
Most of which love the anime nature of Nyan Cat and the meme is really fun too
though most do not have the money to or the idea of what an investment is.

The best way to include these people into the market is to find ways that they can get Nyan Coins without paying for them for starting out.
People love free things and locations where they can get them.

The best things to add are as many reasons you can think of why people would want the coin and where to use it. People need a use for it. If they find it really useful or if there is a large enough of personal gain then they will use it.

It is simple. You just have to prove it too them it's awesome and show them all the places they can get it for free.
