The proof-of-stake benefit is considerable if you hold your stones. Accumulate enough stake and you can reap (POS 'mint') new coins faster than you could POW mine them. Less volatile than many cryptos as there is less dumping (likely due to the inducement to keep one's stake). In essence, a stabilizing factor is inherent in the very design of the coin. This is an intelligent coin. Not another copy-and-paste litecoin knock-off. Nor is it a coin with gargantuan block rewards flooding the crypto ecosystem with a gazillion meaningless new trash-coins worth microscopic fractions of a penny each. That may be exciting for noobs, but it gets old fast. So it's a coin worth mining, and I'd also recommend buying outright. Sell off your crappy coins and move into quality. Really, this and Vertcoin are about the only two I can take seriously (barring Litecoin and BTC, of course).
