just because some people don't pay their taxes when trading bitcoin and cryptocurrencies that doesn't mean bitcoin is affecting the economy of the whole country! these same people would never pay their taxes when they do other things so the economy didn't change because of them.
But the economy will change because of bitcoin not because of people.
economy can change because of people. like, how productive you are.
if someone know about bitcoin than they just dont care about it, what happen? economy's country can be better because of how great people in there. without bitcoin, country can through any obstacle if they have productive people. so, people can change something
