It is true. The new marketing tactics for most ICO projects nowadays is to conduct airdrop to create hype for the project. And this creates a false hype and fomo.
Most of the ICOs had been in the red and not making extravagant profits like in the past. So everyone has to be more selective nowadays
I never liked Airdrop. It made me go crazy, because when the ICO coins after being listed on the deal, the people holding the coins when joining the Airdrop will sell it all at a low price.
