I'm curious and sort of trying to differentiate these two. What are the cons and pros of ICO and Airdrop? why does other cryptocurrencies use airdrop and most of them use ICO?
Both are just a ways of promoting their project before it totally launched in the community. But mostly airdrop isn't bring a good benefits to the participating members for some of it are just scam. Investors will look for ICO not for airdrop because it give them chances to buy coins in bulk and they can also determine a legit ICO.
