The concept of bitcoin is so revolutionary that even now people have troubles understanding it, while fiat currencies are created by those at the very top of the totem pole and the rest of the population has no option but to use them or be penalized, bitcoin is a currency which adopts the opposite approach, bitcoin receives its support from the people that use it as each one of us does so willingly, so while some support from the government would be nice, we do not really need it.
People who actually find it difficult to understand the revolutionary concept of bitcoin, are those who don't really care about bitcoin or those who think that bitcoin is just a parasite or an asset that won't be valuable in the future. and also because of bitcoin risk with high volatility.
Even though bitcoin implements technology that is needed by everyone.
Developed countries are starting to accept bitcoin but some developed countries are also banning bitcoin, this is due to the impact on bitcoin technology which is decentralized, cannot be regulated by anyone and is also too transparent.
Supported or not by a strong country, bitcoin will still grow as a revolutionary digital currency due to the support of a strong community.
The government can only prohibit it through the regulations they apply, and cannot stem the growth of bitcoin.
