I am proposing to Poloniex a 2 week period. First day investors getting 15% bonus, then 14%, 13% ...

At the end of two weeks, as long as some minimum percentage of the total amount raises is still coming in, it will be extended. 1/14 = ~7% so say 3% threshold. Once we get a day where less than 3% of the total is raised, then that announces that there will be 2 or 3 more days and done. I dont want to drag this out for more than a month, so max is 4 weeks.

This will give enough time for everyone who is paying attention to get their proportional share. No limits for total or for individual. I guess a minimum of some sort dont want to be dealing with satoshi level shares. Such things for Poloniex to determine

5% bonus for BTCD or NXT deposits

At the end of the IPO, I put in my assets and get my share calculated along with everyone else. Then since it is already on Poloniex, they send the amounts to everyones accounts and trading starts. Its actual instantiation will be as a NXT asset, so it will also trade on NXT AE
