Russia will not be the capital of the crypts, that's for sure. Among the politicians and in general representatives of the authorities of this country there were very contradictory views on the future of the crypto currency in this country and I saw in their statements more negative than its adoption. What is worth mentioning is the draft law on the criminalization of the use of crypto currency as a means of payment submitted to the State Duma of that country, that says it all. In my opinion, with the current authorities, the crypto currency for the people of Russia will be closed.
No place can be the capital of crypto. Sure, some countries will tend to adopt it more than the rest pretty fast and that sure speaks well for the benefit they stand to gain as early adopters. I see this space as a decentralized space and coupled with the fact that Russia itself is not really certain where she stands in the whole thing, still begs for question. I believe as time goes on, a lot of countries will start seeing the benefit and then there would be a global spread of usage than a country trying to control things they know cannot be controlled.
The thing is dicey. The country that will become the capital of crypto won't really be determined by the country that has the highest usage. I see it being politically determined because cryptocurrency will become a very big business space and the world powers will most likely influence it.
