I'd like to understand what's Airdrop and how does it different from Initial Coin Offering (ICO). Ideally in some general way.
Here are some example contexts:
The tokens will not be distributed as initial coin offering (ICO) but rather as an airdrop. "IQ Tokens will be airdropped into the EOS distribution list in late February," Forselius, told to Inverse in February 2018. Source: Wikipedia.
Blockchain-based encyclopedia startup Everipedia announced plans to distribute its IQ tokens in June through an "Airdrop" instead of taking the Initial Coin Offering (ICO) route. The move would probably help bypass increasing regulatory hitches for ICOs. Source
