I think it's still underpriced. I think it's clear that the market wants more PoS coins to choose from with different features. All that Whitecoin, Yellowcoin etc. are doing is using the Blackcoin name, but not really adding new features or design. That's why I sold my Whitecoin and bought Cinni. Cinni is the clear rival to Blackcoin right now, since it is the only other coin with low inflation PoS and innovative features. If the dev delivers on the new features then the price should go up dramatically. Cinni has innovation that Whitecoin does not, yet it is only half the market cap right now. That means there is lots of room to grow. Also people love the small total amount of coins of only 15 million.
