When participating in an Airdrop, you shouldn't set too high expectations for a project because there have been many projects that promised but didn't deliver Airdrops to users, a recent example being the SUI project. You can participate in multiple projects at the same time with the mindset that you may not receive anything from the project.
Yeah, because airdrop isn’t guaranteed and there are no fixed rewards they will give you, if you’re lucky then you can get big rewards even you will not get nothing, it’s depend on your activities on their platform, now the rules is very hard in airdrops, so that's right we shouldn’t expected big thing in airdrops.
well honestly when a project is releasing their own blockchain probably layer 2 and is being invested heavily by certain companies and take example binance labs, its almost guaranteed that they definitely gonna have token at some point and there will always be some allocation for community. thats what I see from many projects i've seen some pattern here.
but definitely as you said, never expect to get airdrop as if the team owes us something because well they don't usually thats what happens whenever there's announcement that airdrop will have certain criteria to qualify.
some people are so hard on pushing to make themselves entitled for the reward but in reality its up to dev themselves, they can be making some ridiculous rule to qualify for airdrop and I guess they could get away with it since usually airdrop never disclose criteria from early because otherwise it will get farmed hard by bots and so on.
thats the thing its all about trial and error.
