I read thread on how to choose an Altcoin and noticed that nobody who is looking into investing has even mentioned an airdrop.
So why do so many ICOs give away their tokens if no real investors really are checking the free token giveaways?
Its part of making a strong community that can support your project and a marketing strategies also. ICO's makes a lot of airdrop because they need to attract more people on theirs site and pages, or group I think this is one of the requirements when you are listing in a good exchange, to have a strong support and more ways to communicate with your investors.
