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.
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.
I agree with you that usually different airdroops, bounties, shit coins, and new defi-projects are lotteries. You can be lucky and earn a lot of money, but unfortunately there is a statistic that the majority of people lose money or time in such strange things, but don’t earn anything. So it is better to invest in something that is likely to be less profitable and less risky as well.
