By some countries maybe.
Most of these countries did legalize cryptocurrencies but I don't think it is accepted as a digital asset because we all know how will they react when it comes to something that people would earn and them not getting any taxes from it. I guess this is just mainly for the protection of the people that would use it in their country.
Now bitcoin is not issue because many governments realizes they cannot stop this just because of this now few are feeling on other side and implementing new laws which are working for many like recently I read in few countries they are taking taxes and KYC policy is also working very stick so from this I am feeling hopefully in near future we will have some good number of countries those will accept this and have some good amount in taxes.
We will be seeing that in the next few years.
KYC might help some platforms, mobile wallets or exchange but I don't think that would directly help the government. Tax will but I hope they continue what they are doing by just making laws or regulations not to tax Bitcoin or other cryptocurrencies but just to take care of look into the people using it and giving them protections to scams and hacks.
