Government resent bitcoin because they can't control it like they did in 1971. Very soon, it will be illegal to own bitcoin in some countries, not because bitcoin is bad, but because bitcoin gives you the power to own your money.
So far, I think many countries have not legalized and even banned bitcoin because bitcoin does not yet have the capacity and quality needed to be recognized as a currency. But after reading this I started to realize, bitcoin is able to create economic independence for individuals/societies which bureaucratic makers are so afraid of that's why many ways are used to stem the popularity of bitcoin and other cryptocurrencies.
At the same time, it makes me regret why I didn't really learn and understand bitcoin long ago.
