Heard this theory the other day,
Central Banks are buying Bitcoin, in order to crash it. When the crash happens, those who invested in Bitcoin are going to want their money back. When they do, it will prompt politicians to regulate Bitcoin, which is how they will gain control over the price.
Regulate bitcoin? Ah-huh. Sure.
Naughty mathematical code, naughty! Do what the government tells you to do, next time!
