I have earned some there, but i would not go so far and buy it... Its still pretty cheap and it did not pump as much as all the other coins, rewards are pretty low... I think they did some hardfork and now its harder to get good rewards... I guess if you are Russian and can blog in their language it could be a good deal... Still as all crypto market is growing they can pump someday, but i would put my money on something else ;)
