I think this is because of excessive fear, it must be admitted that the number of haters who pay for all media makes many countries afraid and thinks that crypto is a scam so it chooses banned cryptocurrencies.
The government banned cryptocurrency because of concerns that financial transactions could not be controlled, the movement of money between countries through banks would be government data for the calculation of the fiscal year. But with crypto transactions all data is missing, so the government does not have accurate data on how much money is circulating and how many transactions occur between countries.
