For this moment, I think it will take time for either Russia or any other country to emerge as the next dominant superpower. We know the United States has won the title for a very long time but the predictions of the birth of a new power are starting to emerge and that is what we will continue to see in the next decade or so as new superpowers emerge.
For Bitcoin itself may be part of this new world order. Not now possible but may eventually be adopted by some countries. It all depends on how well they can make it visible and how much the public will accept it. For the final outcome of this situation is just predictions and predictions only.
The strength of the United States lies within it's currency. The USD remains as the trade and reserve currency of the world. And this enables the US to loan trillions of USD from the creditors every year, at near-zero interest rate. And this is also one of the reasons behind the inflated military budget of the United States (~$600 billion per year?). Other countries don't have this luxury. So they are forced to tone down their budget. Now I don't think that this situation is going to change sometime in the near future, especially as currencies such as EUR are sliding down steeply against the Dollar.
The strength will vary on military strength as well. But given the fact of what happened Afghanistan, this made the conclusion that the military strength of the US had declined. In many aspects actually because in the race to Space, China had won already and in the case of military weapons, China had the hypersonic as well.
We have not really seen Dongfeng17 in use and hope to not see it because warheads flying all the way across the world are not going to make us survive even if we are a hundred miles away from the target. This is why they do have the chance of winning in a military confrontation especially if they can hit the Whitehouse while they are not in the Mexican gulf.
