Team already hinted on a 25K ZOI Zoinode with high ROI when the price was only 0.02 cents. I mined zoin myself for almost 5 months and got enough to run one masternode and I was also able to pay for my mining costs. It is also a question of investing in long term development of a project, which btw can all be found on the roadmap, discord (before slack) etc.

I know many miners who just mine and dump it all on the market to make come quick profit. Miners have been able to mine over 17 million zoin...please learn to invest and adapt. 

The decision was made by the community. And the 25K ZOI + 65% of block reward is actually good for the network stability. In the end masternodes are made to stabilize and improve the network.
