Let us expect that there will be a few countries that will go against it as it can't please all of them. I think these politicians doesn't really see the technicalities of bitcoin but they only see it simply as an investment asset and, as long as it can potentially give profit to the investors, that's how they understand and giving it an importance.

The impact, I guess not that much for those politicians and countries that doesn't really have a say about bitcoin or blockchain. They will never know how many bitcoin people are there in their country unless there's an established exchange in their place and being used by most.
