is actually good advice, especially since there are many airdrops that are designed for suspicious purposes, such as harvesting personal data or even asking for payment to gain better access. An airdrop is essentially a way a blockchain or crypto project distributes free tokens to the community or potential users, usually for promotional purposes. However, currently there are many fake airdrops that take advantage of people's desire to get free profits
It's a shame and I totally agree with what you said that airdrops are actually given for free to those who are interested, because it is indeed a means for promotion. But currently, it is used to seek profit by doing a lot of work that must be done, and not a few even ask for payment on the grounds of gas, and there are many ways to attract people but in the end it is disappointment that can result from what is done.
