There are quite a lot of good projects, but those that pay the community the proper rewards are very rare to find. Sometimes projects that are already good and listed on Exchange Tier 1 actually provide small rewards for the community or unfair distribution. this will raise the ire of the community and the project will forever be marked as a fraud.
Of course, not all projects compensate early participants fairly, and some do not pay in the end, as happened with the SUI project. Some projects set futile conditions for those who qualify for Airdrop, as happened with Starknet, or rely on discord rules or points, and so on. Additionally, some projects do not announce airdrop dates for early participants who interacted with their ecosystem and interacted on their own network. Hunting these airdrops and getting rewarded depends on luck, so there is no guarantee. Even some get a small amount of tokens, and it is possible that the participant paid more fees for participation than what they claimed their Airdrop. Still, frankly, I find that this year, many promising were launched that were listed on Binance and the TOP exchanges in the market. Hence, there are plenty of opportunities for anyone who has a surplus of funds and would like to try his luck in the airdrop arena.
