Bitcoin actually doesn't require approval to be used anywhere. You can use it as long as you have internet connection and a device.
Countries "approving" bitcoin just makes it actually legal to use and accept for merchants. correct me if I'm wrong
Yes you are totally right, i think the exactly same. The goverments don't want to miss taxes about cryptocurrencies anymore. Everyone is using bitcoin nowadays and the number is going high everyday. I think in near future all the goverments will accept crypto moneys and will have the taxes. It will be the way i guess..
The legality of bitcoin is very much the governmental way to make money of cryptocurrency. Its a legal, go signal for businesses to adopt crypto while at the same time some of this share will go to governments via the tax system.
Bitcoin needs a strong investment to become more stable and attract more users, making it more popular. Bitcoin therefore requires approval from the states. This is an important step for Bitcoin so that it can thrive in the future and realize its full potential.
