This may happen. But bitcoin is not always approved by governments,
and we can not say that all governments in the world want bitcoin.
So bitcoin can be a global power, but not in all countries
I must agree with you. Bitcoin can be a global power and its getting popular but still until now their are some countries that banned cryptocurrency because their government doesn't allow it to be legalized in their country . But yes bitcoin can be more bigger and has a big possibility that it will become a global power.
