I have noticed these two blockchains (polymath - the one with ads on coinmarketcap) and Hydro (a fintech startup) doing 100% free airdrop. Thoughts from the community? Is this better than ICO? I think it makes the project better for developers and can lead to more innovation. Many blockchains are open source...then they make me as a developer buy access. It doesn't seem like this is the future.
