You forgot about dev team share. So, 0.0005 - 20.63% = 0,00039685 ETH
And you will have to use PayDividends function of the smart contract (it is not automated for some reason) and I guess you will have to pay about this amount for the gas for this transaction (may be exactly for this reason it is not automatic).
So, if ICO will attract 200000 ETH - divide it by 2.
It is good to know. Thank you for your calculations.
It is easier than to find Satoshi. Based on open info from the profile of topic starter probably the whole team is one guy (which is absolutely ok for me):
Great idea and no reasons not to trust that devs trying their best to make great stuff... but if someone smart finds another bug I guess he’ll be smart enough not to show it now but wait until we collect nice fat jackpot. ((
Another concern is that smart contract code which is a product itself is publicly available. Anyone can deploy it today to start a copy of this. Literally copy it and deploy - voila! Great threat to global leadership. ((
