A few years ago airdrop pay to the hunter much but gradually that trend decreasing. Although we know of some airdrops that have rewarded hunters but the number is certainly not high. While some airdrops pay, most airdrops waste hunters' time. Telegram-based airdrops have emerged recently, but not all will pay hunters. Not Coin rewarded its hunters and more projects are arrived. There is no way to say that all of them are legit projects. Scammers are always active in these areas. Therefore, before joining any new airdrop, one should take a decision by observing these issues. Airdrops and bounties had a huge impact a few years back but now they are going to be worthless.
