These three countries, namely China, India and Russia, have a lot of people who have cryptocurrencies, whether it's from mining, trading or the result of an initial investment in a project that was launched such as an IDO, IEO or ICO.
And the three countries also want to accept cryptocurrencies as digital assets or means of payment, so my guess will be very easy to accept. Logically, some of its citizens now have a lot of digital assets from cryptocurrencies.
