Game between project owners and retail investors:

- When retail investors have a strong consensus on interactive airdrops, project owners use airdrops to cheat retail investors of GAS

- When retail investors believe that points have wealth opportunities, project owners use points to PUA retail investors

- When retail investors believe that staking is "both eating and taking", project owners use staking to trick you

There are even more awesome projects that do interactive airdrops/points/staking all at once, and cheat you for several years without issuing coins...
