I tend to agree, crypto market is still small though it underwent in a venture, we're just probably thinking that it is huge coz we are inside it, but once we go outside of the market we'll see it as just a small fraction of the world's finance. Would this impact the economy of the country? Maybe, as for some countries that has a major business that includes crypto they might be affected. At the end of the book, there's no way someone could stop the crypto, it does not take any from what is existing or stepping on top of the current laws, there's just no reason to stop the crypto. This is just a very impossible "What If".
