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.
Obviously, an airdrop is not a sure way to make easy money. Most airdrops promise most likely not going to be true. They just projected the price to have many participants in their airdrops, but it will not be going to happen after the distribution of tokens. If money is easy to earn by just joining airdrops only, many will come here and join in any airdrop.
Remember, one thing that this is 2020 now and none will give free money. You have to work for them or you have to do physical work or whatever the procedure is. I can only say that it is not so easy and not so hard to make money in the cryptocurrency. Do some research then comment. I am a student and cryptocurrency is my only earning way.
Some airdrops will give easy cash but that's rare. Only a few airdrops that have strong and unique projects will likely give free money online. If you want to earn money online you need skills that need in freelancing jobs or rare skills that most need in 2020.
