Based on my experience airdrop is a small amount of earning. No one will give you a big reward, but if you give and do your best effort then you might get a big reward. But as of now that the market is down the airdrop earning is just a way for you to add up some coins if you don't have the money to buy some coins. It is not hard to earn a big token in the airdrop the task is just so simple. In looking for a good airdrop you have to check their airdrops careful, if you do not check it carefully you might end up joining a scam or not so good airdrop that will give you a small amount for token even if you work hard for their poor airdrop. You have to have a criteria in finding some good airdrop so you will not have a bad experience with the airdrop.
