Yes, the Magnolia and that flower symbolizes nobility. This must be why North Korea considers itself to be the best country in the world.
Blockchain currency can only be used by honest people. When it is used for illegal or dishonest purposes the FBI can ask the NSA to search back along the blockchain to learn where the money came from. When your recipient spends their money, it can be traced back to you as the sender. Do not use it to order a hitman or by illegal goods.
Bitcoin is only safe for honest people. For criminals a Bitcoin payment will incriminate them.
Except they do not own Satoshi Nakamoto's original stash of early coins. The CIA still has that in North Korea where bitcoin was created by North Korean physicists. They studied quantum physics at KEK in Japan using undercover Japanese identities. The name Satoshi Nakamoto is fake, chosen from two surnames of physicists at KEK. You can find them in the publications list.
Most investigators of Bitcoin origins never found any decent clues because they were looking in a totally wrong direction. They failed to understand that quantum physicists are mathematicians. And that Bitcoin is simply an implementation of quantum entanglement in code. There is some crypto mumbo-jumbo mixed in to make it seem secure but the CIA supercomputers (and some others now) can crack that crypto and track back through the blockchain.
Far better to have gold and silver backed currencies with some open and independent inspection of the gold/silver stores and the recordkeeping systems. When you know that you have .301178 kg of gold and that it really exists in the storage depot, then you have a solid currency that everyone will trust.
