Airdrops are now becoming irrelevant, most of them are there to scam people look at ltg they just dump their coin and run away. Be careful
It really depends, I am working on a project and we did think that airdrop could be useful but the issue we see now is that people expect to get rich from it. Thus, often the wrong people join and only damage the entire project
We will probably do more like a bounty and without things like social media and alike. Since it fits the project we are building. Still, given the current situation we are considering postponing everything
