The worst thing that will happen to Bitcoiners in a country is when the government bans its use. If the government criminalizes cryptocurrencies it will be difficult to freely engage in crypto endeavors secretly. Many people will not be willing to take the risk of using Bitcoin illegally. The best option for Bitcoiners in such situations is to move to a crypto-friendly country.
I think such can only be actualized if the government authorities are amidst of scientific entrepreneurs.
The US has been able to establish a sound regulatory framework to regulate the crypto industry. Many countries have not been able to have the same level of expertise in regulation, so they have decided to place a ban on it. We have been seeing an increase in the acceptance of Bitcoin in most countries through the approval of Spot Bitcoin ETF and hopefully, this move will move to other countries in the near future.
