I agree with you. It was and still is being over hyped.

However I am enjoying the large price fluctuations.

It has been quite profitable for me to buy when everyone panics and sell when the price goes up.

Long term it will succeed in my opinion. Is there any need or use for it?

Nope.

Yet when someone comes out with a Primecoin payment plugin I will be taking it as payment.

Why? The fact that it has no use is not relevant. Other people give it value.

All that matters is I continue to make profits with it.
