What happen if the crypto currency stop? Is it big impact in Economy of all Country?
I believe the crypto space is somewhat independent, that is, it is not fully in affiliation to any country's economy whatsoever, but however I can say the individuals in that country can in one way or the other contribute to their economy via crypto. Let's take a look at most exchanges or crypto projects based in different countries, I believe they are subject to that countries regulations thus likely to pay tax and so on, thus it is also contributing in a kind of way. Also, with the level the crypto space has grown to, I believe it can only keep growing because it has succeeded in touching lives, being implemented in many platforms and so on.
