I heard my friends talking about free token airdrops, so I was curious to learn more. Turns out, an airdrop is when blockchain projects distribute free tokens to the community for promotion, which is quite common. Some people use tools to automate the process, creating multiple accounts and participating in different airdrops simultaneously. It sounds reasonable, but I think you need to be careful. Using tools for airdrops saves time, especially when many projects are launching airdrops at the same time. However, each exchange has its own rules, so running tools isn't always allowed. Additionally, not all tokens have value; many airdrops end up not being worth much. I realize that participating in airdrops actually depends on the legality of each exchange and project. If you decide to use tools, you should choose reputable ones and understand the risks beforehand. Anyway, airdrops are just a way to learn more about new projects, and you shouldn't expect too much profit from them.
