Even if #Bitcoin’s technology came from intelligence agencies (which is likely), it doesn’t matter - it became open source. It’s built on proof of work and secured by the world’s largest distributed supercomputer. No shitcoin has ever come close to competing with that hash power. That’s why BlackRock wants your bitcoin. That’s why they want you to borrow against it instead of selling it. They know what you have. Hold bitcoin in cold storage. That’s it.
