Well, from there we can consider whether or not we want to spend capital first. I also participated in airdrops that required capital, but I chose a small capital and I could afford it.
For example, some projects require us to bring a little capital for daily transaction costs. When it doesn't cost a lot of money, I'm ready to do it and I also won't expect too much from what I can get.
If the capital is small, maybe we are ready because some airdrops require us to spend capital first.
However, we have to study the project if it is likely to succeed we can follow it because how to find rewards with capital first, we must not lose.
Because several times I followed it, the project failed, this happened in the past.
