When is it Bitcoin's official birthday?
My opinion is that Bitcoin was born with the release of Satoshi's whitepaper on 1st Nov 2008.
thats when bitcoin was conceived
its birth must be the genesis block
I would have thought conception was the moment Satoshi started thinking it through and *began* writing the whitepaper. The gestation period would have been the time between conception and releasing the idea to the world (ie, birth) with the whitepaper.
Wouldnt that make the genesis block our Bitcoin baby's first words?
