Just like NEM - make a thread, let people pay some coins (not too many), let it run for few weeks and the divide the NXTs between everyone who has take a part in an IPO.
Guess you weren't into NXT during the original thread release? Since that is exactly how it went.
NXT's investment timeframe was run for 6 weeks (lateSept - early Nov). Only 73 people were interested in it, which is why there was only 73 original stakeholders with amounts invested between .00000001-1 BTC. The rest of the posters called scam or didn't believe in it. BCNext called it off early at 21 BTC for who knows why... might have been the "21" type of feeling aka 21=21,000,000(total ever BTC created) type of look. Or maybe BCNext worrying about too many multiple buy-ins, or something else.
The only people that call it unfair now is those that missed out on it. Especially when the price was still 1BTC = 1M NXT during the first 1-2 weeks AFTER NXT was released.
You can have fun reading the original thread if you want:
