Well yes they afraid on legalizing or implementing bitcoin because bitcoin is decentralized coin which no one can control it even the government will not able to control it. There's still countries that not implementing bitcoin because they see bitcoin as a threat on their society.
It doesn't mean that bitcoin is decentralized the government is afraid of it. They can still use their authority to control trades that are involved with bitcoin.
That's why regulations are coming in and by this act they are gaining power to predict on what are the things that a trader needs to follow so that he won't violate the rules that was set for bitcoin traders.
Let those governments that are skeptic of adopting bitcoin, give them time to study if its beneficial to them. I'm sure of that they knew it that they can also take advantage by taxing bitcoin transactions through local exchanges.
