I don't know, all altcoins end up the same and that makes me lose faith in altcoins and what's worse, no matter the technology behind it, it's still abandoned after more hyped coins even with lower grades, if Peercoin can be adopted by many communities and or its network is supported by many developers, it might increase interest again, but what can you do? Nothing will last long, the crypto market adapts faster to something new, if a product is too late than others, it will lose interest.
The AltCoin market had muchly been dominated by seasonal Crypto Currencies whereas, as it attributes potential valuation of prospects, and as much it earns investors interests to invest on, it's usually somehow maneuvered in the terms that's best known by the inventor and teams leading to the crash of the coin which we may assume they're core driving values basically by hyping.
While several issues had occurred in the AltCoin space with no specified problem identified to why the project has to fadlarge, investors becomes skeptic and loosing their interests even when the dead coin awakes again. This also had made lot of investors lost interest entirely in the Alt market at large.
