Now the point to ponder here is that it could be the strategy of the project launchers to show some peeps winning the Investments to gather more attention or else it could be real. Just go and check out your luck.
Honestly speaking, luck is rarely behind success of airdrop winners. It is simply how well you understand the procedure of eligibility set by the launcher of the project, and diligent completion of the tasks to qualify for the reward. There are also bad players in this sector who reward to few participants and rests are declared as ineligible. However, I have personally experienced that reputable projects, such as Arbitrum, Optimism, Manta, TIA and Dymension have fairly distributed reward to their loyal participants.
