The airdrops that you have presented are very interesting. Personally, I think that this type of initiative benefits users, who can obtain a free sample of the new product, but also to the companies that are looking to promote their tokens, since this way it is possible to make a good publication and also clarify the doubts that could be presented at the time of using a token or a platform.

Excellent post, very good summary for people who are always looking to be aware of the trends of this Blockchain world.
