Early users must not be forgotten, and in fact, should be given higher weight as they had been with the project since the inception and supported the project with their time, effort and early knowledge contribution. Rewards should also account for interacting with $ZZ and when they purchased it, and how often they interacted with ZigZag exchange before $ZZ was launched. So:
1) Early users/adopters
2) If they interacted with ZigZag exchange before $ZZ token launch then that must be given consideration
3) If they also purchased $ZZ soon-ish upon launch then that must also be rewarded.
Dont forget how the base was formed!
Definitely reward early users More.
