Thanks. That shows when the bonus and asset distribution happens (January 26th). But when are backer ranks determined? Was there a snapshot already? Or, can I buy more NXC up until late January to increase my backer rank?
The backer ranks are determined by the ICO transactions. It means that the Nexiums you purchase from the market after the ICO don't count for backer ranks, and that you can freely manage your Nexiums (send them on another address, sell them etc), it won't impact your backer rank calculation.
