My suggestion, if you see a potential from a project that provides airdrop, then you should do it. However, the task of airdrop is usually not too heavy. It is very difficult to determine which projects are really potential. In fact, projects like Hamster are very big, and people think that it will provide great benefits, but the current fact is that many people are disappointed. However, a project will not be known whether it will be profitable or not until it actually pays and enters the market. So, when you feel that the project is good enough, then work on the project.
Agree, indeed the task is not too hard, but the time provided quite robs us of ourselves, when we have to follow up on whatever we have to work on. Finding the potential is, of course, also difficult, because based on the number of participants, it seems that many are paying accordingly, so many are disappointed with this incident, but everything is determined as such.
In my opinion, usually if there are too many followers then it will certainly not be good, but if the participants are ordinary, maybe it can be profitable. Everything is now determined by you if you do feel a good project followed but if otherwise abandoned.
