Believe me my friend, anywhere in the world, it is not easy to make money. If you see any airdrop that promises 100$, 200$, 300$, 500$ and above just for referring peeps, or sharing post online, then it is atmost 99% fraudulent.
Sure, they are made with the intension of looting people, getting fake or viral publicity for their tokens. The plot is:- Due to cool and trendy looking airdrop more and more people come to that particular project. There is high conversion of people into investors and thus project gets what they want. However, airdrop value doesn't last the same since coin value goes down too when these same investors dump their coins.
Likewise if you see trade signals that promises certainty, or bounties that promises you a fixed price for your token, be wary. It is not that easy nor realistic.
Arrghhh! Bounties would be first thing one must study carefully before investing their valuable "TIME". It takes lot of time to get credited and also you need to wait for the coin to get listed which is always ambiguous thing by the way.
