When I open Instagram, I see many people promoting projects like Tapswap, Hamster, etc, and assuming that the audience is stupid by promising a great life and a lot of money. But there is a positive point here because regular people are learning a lot about digital currencies. In my opinion, users can only make a few hundred dollars from these bots, which isn't bad, but the reality should be made clear to people. Do you think it's really that easy to get rich with just a few taps?
One thing about airdrop is that it is always unpredictable, and I think when the notcoin airdrop was on people could participate by tapping their screen and many people people didn't believe such method of airdrop could generate money for them. After the notcoin airdrop other projects emulate the method of notcoin airdrop and people belive taping can generate some cool money for them. It is not a guarantee that just tapping can earn money, but still anything can happen.
