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
Yeah I agree with you. There is no need for some approval for you to do cryptocurrency or bitcoin. If you have the capability to do it, then no one can stop you. Maybe there are some countries who are announcing that crypto is supported by their government but it doesn't mean that the government approved it, they just make it legal and support it in all aspect.
