Because masternodes means HighOnCoins from YouTube will pump the shit out of your coin like he recently did to ChainCoin

Look at the state of that!

In case you missed it: His theory was that everybody should keep buying and holding, with nobody dumping, and they'll be able to get it to $100 so all the MN owners will rake in the profits.

I'm not sure he'll be winning the Nobel prize in economics any time soon...

Anyway, I think this little experiment of his is what's brought the masternode hype back.
