Did Satoshi choose to publish Bitcoin's whitepaper on Halloween as another Easter egg?

Satoshi Nakamoto announced the Bitcoin whitepaper on a cryptography mailing list on Halloween 2008.

Halloween is the carnival time, a ritual day when one can pretend to be someone or something else, whether a comic book superhero like Batman or Superman, or another eternally popular choice for Halloween, a Ghost - a spirit, much like Satoshi, that is neither dead nor alive.

The carnival tradition goes back hundreds, even thousands of years, and there is no more apt day for the creator of Bitcoin to reveal the persona of Satoshi Nakamoto than Halloween.

Whoever created the pseudonym Satoshi Nakamoto, they likely came from the cypherpunk community, a variegated bunch that was united by a common goal of using cryptography to curtail the reach of the Hobbesian Leviathan.

Finney was the first person, outside of Satoshi, to run Bitcoin; he was the recipient of the first Bitcoin transaction as well.

His early involvement in Bitcoin and prior experience in programming has led many to believe that he was Satoshi.

Had Finney been involved in the creation of Bitcoin, then for the lover of "Mystery and paradox" named "Hal", revealing the project to the world on Halloween might have had additional meaning.

For Satoshi Nakamoto, the creation of a decentralized electronic currency that was beyond the purview of any government was an ideologically driven endeavor imbued with symbolism and ceremony.

The quote has also acted as a watermark, a timestamp that certifies that the Bitcoin network was started on Jan 3, 2020.

Some have suggested - the birth year of Satoshi Nakamoto - 1975, the first year the Americans regained the right to hoard gold.
