“When you do a Bitcoin transaction, it is not related or attached to identity. You do not need to create an account. You do no need to register. You do not need to provide ID, or name, or location, or address, age, gender, race, religion, nationality, nothing. You don’t even need to be human.”
-Andreas Antonopolous, in the YouTube video ‘Bitcoin for Beginners: Bitcoin Explained in Simple Terms’, in 2017.
