Currently, there are no airdrops that give big rewards to their participants because currently they are doing the airdrop program just to increase the number of followers on social media and hope that their coins become trending because many people repost their coins. and we no longer find airdrops like Uniswap and Apecoin. So currently many people are retiring to participate in the airdrop.
There are numerous Airdrops which offer a good reward but people often fail to get it due to unawareness and also they don't know where to find information about good airdrops. Sometimes they find trustworthy Airdrops but they become illegible for getting the reward as their work is not according to the rules of that airdrop.
Currently Airdrops are giving profit to its participants if an individual invests some amount in Airdrops but we as humans always focus on free ways to earn money. If we work accurately, find a profitable and trusted Airdrops and then do what they ask for so they will surely be eligible for getting an Airdrops.
