Okay this is such a scam. 500 MN will be running all at once, with 1.4 block rewards making it nearly impossible to have any decent ROI @ 3 mins blocktime. Aside from devs getting their sweet moola, running a masternode @ 3 min blocktime means you'll get at most 0.8-1 blocks/day - and you need around 5800 blocks to get the 8000 needed. So, enjoy your ROI of 1.5-2 years. This is pure gamble on the coin's potential worth - but the ones at the top of the pyramid will probably dump way before the average Joe wants to make it worth for him. And your case-use is nothing new, nor the application (according to the whitepaper) is anything worth investing huge amounts into - since such a poor roi would only be worth if it's Dash value or the like.
My advice, at least limit the sales to around 50-100 nodes and burn the rest. And don't keep 4 years worth of coins to yourselves. At most take half a year of rewards for your fee. Any decent investor will do the math I did. What you try to get here is stupid money - any clever money won't invest unless you clear these things up. And you people who invest in such things - the only money you might get out of it is from the one that came after you.
Geez, such projects are giving masternodes a bad name.
As was mentioned before every user is entitled to their own opinion, it's not like it is being forced down your throat.
The Pre-Purchase Phase might not even sell out making the whole 500 Masternodes concept moot since the unsold coins would be burnt.
Your maths doesn't take into consideration luck and frequency
Another option you never explored is that if ERZ gets bought up at 10c, 20c, 30c, 40c, 50c, then gets listed on Exchanges and the price is double, triple, quadruple, quintuple what was initially invested wouldn't that make your ROI quicker....
Same goes for Miners, $10 worth of coins mined in a day could very well be $100
Regarding the 1M ERZ Development Incentive, do you really want the Team to just leave ? They need to have something to bust their asses for !
5M ERZ will be locked up for Lending and Referral Contracts
The Unsold portion of ERZ from the Pre-Purchase Phase will be sent to a burn address... this is all self explanatory.
