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?
Well, that is a simple market strategy because airdrops kind of create traffic, so to say. By giving away a portion of their tokens in the name of airdrops, they draw the attention of every one to their projects and investors are part of the people. After getting the details about such ICOs they invest, so you can't say airdrops are irrelevant. They are meant to publicise the projects.
