This is very good. I think this is about providing security to the people and not to stop them. The youth will have more benefit in this because they have more years to stay around and can invest to hodl more cryptocurrency investment. They scare of scam exchanges will be reduced because the government making sure to secure exchanges in their country.
Governments allowing specific exchanges to perform the trading of cryptocurrencies limit the usage. The reason for which the government have taken the decision is really appreciable and a forward thinking compared to the countries that make a direct ban of cryptocurrencies. Slowly the country needs to provide way to spending, through which the real usage of crypto can be understood.
