Airdrops forms part of the avenues for making money in the cryptocurrency world. Most of them comes in a very easy way by just filling up forms with your ETH address, however, airdrops are faced with the challenges of "which is the real one?" Fill 100 forms for airdrops and only 40 pays you and even with that only 2 to 3 gives quite a tangible amount of money when exchanged on the market.
This issue has dwindled most people's interest in participating in airdrops.
