CBN do not call for regulation but for ban, the countries that are regulating cryptocurrencies are even making it difficult, example is the new crypto law in India that wants crypto capital gain tax of 30%, that is huge. As cryptocurrencies has not even be regulated in Russia, the Russia banker wants crypto users in Russia to only use exchanges which they are controlling or they should use noncustodial wallet address that is registered with them.
With the high taxation imposed in India, majority who are dealing in huge numbers are moving out of the country to safe heavens and that will happen with countries that are coming up with regulations that are hard to make a substantial profit.
