So the IPO was ended after 27 days? And people had to pay more and more and more during that time? Nxt's IPO was 61 days long and everyone paid only 2 Satoshi for 1 Nxt on day 1 and also on day 61. So Nxt is still 6000x more fair than NEM

well if you registered first for NXT you got a bonus shares - witch was smaler and smaler, with NEM you payed more for the same amount. Same mechanic done other way around.
