Quite simply, all legal entities are no longer allowed to accept cryptocurrencies as a means of payment, and anyone who would continue to do so would be breaking the law. Given the penalties in that country, I don't think it will occur to anyone to try to do something illegal.
Of course, this does not mean that crypto transactions in that country will stop in terms of payment for goods and services, they will only take place privately between individuals. No government can prevent the use of Bitcoin for private purposes, that is the beauty of the whole system that can continue to operate despite any ban.
