I do not participate in airdrops because I have been disappointed many time but if you are lucky to participate in a good one because there are some that are very good and worth participating in, you earn reasonable reward as not all are scam only that airdrops do not really pay big reward. Take time to do a research and you might be lucky to find a good one.
Don't be discouraged quickly, provided we want to analyze the airdrop program that we will follow then we will not be fooled. The determination to keep trying was very important because the business never betrayed the results.
