Japan's strong and early embrace of Bitcoin and the name Satoshi Nakamoto makes me think that secretly they were behind the genesis of Bitcoin as their master plan to defeat the US dollar and make the Japanese Yen one of the world's main currencies...

That is an interesting theory or....The US developed the plan, knowing they could test it in Japan, as they have with several things since ww2. If it fails, blame Japan lol.
I love reading ppls satoshis theories
