Yes, this happened in my country that Cryptocurrency is not permitted to be used for payment media. They say that Cryptocurrency is dangerous because it can be used for terrorist funding and money laundering. This can have a negative impact on the government.
Anything that can't be controlled naturally won't appeal to the government. They can not check transfers, there is no data about the owners of wallets, no one cooperates with them, so they will interfere with the work of projects.
