Hi.
Interesting to know about airdrop ...
Is it financially profitable?
If it is profitable, then how to earn it right?
Am I understanding correctly ... ... what should I mark on pages as I like and repost their topic. But many people say that this is a waste of time ... is this so? (something like - cranes?)
It totally depends of the project.
For example: Onion, OTN and other try to do airdrops instead to ICO, which in my personal opinion is much better than spend your money in something that you don't know if really worth. But are you talking about a specific airdrop?
