In Puerto Rico, there is no tax on crypto. You can hodl and then once you are a multimillionaire you can just go to puerto Rico and retire. If a country bans crypto or excessively taxes it, bitcoin holders can just move, depriving the country of tax revenue and business while the crypto friendly country receives business, capital, and potential tax revenue. This means there is a price to being crypto unfriendly. A country does so at its peril. Countries don't matter anymore.
The people don't bow down to countries anymore. Countries bow down to the people now.
Unless every single government in the world launches a coordinated attack on crypto, there is no stopping crypto.
