now there are some countries that began to issue a ban on the use of bitcoin, is there any influence on the country and of course its users in economic value?

When a retail website like amazon.com goes down. There are some who claim this can represent millions in lost revenue. The same principle could apply to currency support. If there is a high demand for bitcoin and alts which are banned. That demand often can't be replaced. Its based on value and utility. Banning bitcoin is like shutting down the golden gate bridge or something people need and rely on which can't easily be replaced. A ban on crypto definitely represents negative impact upon the economy of a nation. I don't think there is anyone in the world who will argue with that. The only question is how much of a negative impact does a crypto ban represent.
There is also a side issue where independence movements across the world are likely to embrace bitcoin and crypto currencies to gain further independence from central banks. Brexit, the catalan independence movement and similar social reformation occurring around the world could embrace bitcoin and crypto. These bans could become polarized in the sense that independence movements may be likely to legalized and support crypto while those who oppose independence may move to ban crypto as they are able.
just agree with this , even the affect with indirect affect but it still affect that user who using bitcoin on that banned country
