Ethereum's "birthday" is the day mainnet launched (July 30 2015), not the day people started raising money to work on it.

I work for Ethereum at the Ethereum Foundation.

Sure, that is when the heart started beating, but some pro-lifers will tell you Ethereum truly began when the whitepaper was published! (Nov 2013)

A doodler and computerer. I like permissive/permissionless open source, smart contracts, p2p systems, room-scale VR, and NixOS.

Currently: WhatsABI

The white paper was the marriage, the ico was the conception and the launch was the birth
