Bitcoin, due to its decentralized nature, market cap, and lack of involvement by its founder, does not fit the criteria of a security according to them.
I don't know what SEC has been for over 14 years when just know that fact of bitcoin. And what makes me laugh is SEC really doesn't know the meaning of crypto. Maybe they think centralization like USDT, USDC, and others is real crypto before, and assume Ripple is just like those tokens. and after reviewing and researching they find the fact, that Ripple and Bitcoin are really decentralized. But we don't know what their plan is, SEC is a big institution, there's no way he doesn't know that fact. I think they already bought some bitcoin, and try to create FOMO in the market.
