Is there any evidence to back this up? It sounds too conspiratorial to me. People have a hard time accepting that "small" people can do "big" things, so they come up with more profound explanations. A lone nut with a gun could not have shot the president, it must be the CIA. 19 guys with box cutters could not have brought down the WTC, it must have been the government. Some random hackers or market manipulators couldn't crash bitcoin, it must be the central banks. The truth is that we live in a world where insignificant people can sometimes have a significant impact on history. Then again, if you have evidence for this, I'd love to see it.
