A country does not need to invest money in Bitcoin in order for Bitcoin to help its country especially when the funding of the country is not sufficient enough for its local/nationa projects. All the government need is to stimulate blockchain investors and company to invest in their country establishing crypto-related infrastructure. To do that the government must tailor their regulation in favor of cryptocurrency. -snip-
Developing the crypto ecosystem in the country is the best way for the country to benefit from cryptocurrency. I remember that before my country regulated cryptocurrency, crypto platforms only paid regular corporate taxes and traders did not pay any taxes for withdrawals or transactions, it basically had no impact on the country. But after 3 years ago cryptocurrency was regulated, until now my country gets crypto taxes of around $20 - 37 million dollars per year. And at the same time providing thousands of jobs to people who work in the cryptocurrency sector. That is one example of why regulation and development of the cryptocurrency ecosystem is very beneficial to the country.
