In my personal opinion goverments are intrested on legalizing bitcoin, because they can start taxing from it after all of the rules are accepted. So it's better to stay at the current position where goverments are not intrested on legalizing it, it would be better for people who are using the cryptocurrencies and transferring on platform without paying for transactions
You have your point too.Some countries have been legalized bitcoin because they have seen it to have much potentials in minimizing the economic crisis.But if this happens,they will also get the chance to impose taxes on bitcoin community so it would not bring any good for us since we are used to live here in a decentralized system.
