Of course, if the government legalizes bitcoin as a legal means of payment, then bitcoin adoption will automatically increase. However, because several countries such as Turkey, Russia, Indonesia and several other countries still prohibit it, bitcoin adoption there is hampered. But because bitcoin doesn't just function as currency, it's still possible for us to profit from trading.
The prohibition of Bitcoin in these countries is not related to the fear that Bitcoin could supplant the national currency. The countries listed by you have a rather large shadow economy, therefore, such measures are taken solely in order to slow down the outflow of capital to the uncontrolled financial sector, so to speak. Well, of course, this is also a question of psychology ... if you forbid people to do / buy something, they will do exactly the opposite.
