In my opinion, the masternode and privacy based coins are taking longer to start breaking out because the new money has to learn about the advantages to these type of coins. Just a theory, but I think in a few months when bitcoin hype is pumpin and lots of new people in the space, youtubers making "300% gains on this from this shit coin" video are going to love coins like this. First off if you don't know what master nodes are, you own a certain amount of coins and you can stake them on a computer or rasberry pi you plug in the wall, or you can pay a service to host your coins for you. Good master nodes give you 5% - 10% a year to stake your coins and make them available for the network to do whatever. Only issue is they spike 1000%+ in a few months and then dump all the way back down. Anyways, pivx seems legit for what it is and itsa cheaaap! Try not to worry about 10 - 50% wiggles during this trade, use a small amount of money relative to your lifestyle. You should not care about this trade until it's worth caring about... Plant the seed!
