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?
No investor pays attention to a couple of tokens from airdrops. The main purpose of airdrops is to advertise the project and attract more investors.
Since every project needs money to develop, there are very few projects massively give away in airdrops (HYDRO is a rare example). However, their tokens prices are usually involved in sudden pump and dump game.
