Actually airdrop is one of the best and easiest way to get free tokens but let's discuss how the value of those tokens will be. There are hundreds of tokens sitting in my wallet that i got from airdrops but no value waiting to be sold. However currently there are different forms of airdrops where you can complete a lot of tasks and get paid 1-2$. Moreover most of the airdrops seen from social media are fake and a difficult step for scamming.
