Based on what?? This coin has no real use case that many above it don't have. I'm not sure how you valuate the coin to that amount?
The website also looks like a 10 year old designed it. Highly disappointing.

Check that out may be that will help you out, I do accept development is slower being the First POS Alternate Coin but that doesn't mean it will never develop, Developer is strong is always active Been 6 years and coin is still strong and popular (Not As much as Bitcoin or Litecoin) but still popular some more involvement might help PPC,
Note: Each and every transaction burns PPC so each transaction made in PPC will Burn some coins which will be one small reason for its value rise also.
