The US has grown exponentially before Bitcoin existed and will continue to do so, with or without embracing it. Crypto as a whole is one big hype. It's useless for the most part. What in the last 10 years came out of it?
Many modern pundits and philosophers, while admitting that capitalist economy is the most effective one in our current global economic system, suggest that it's starting to slip more and more, and, perhaps, will completely stop working in the near future. Again, it's not that any other economic system we know of is better, no it is not, but rather a completely new economic model has to be invented, and I believe that Bitcoin is going to be a part of that new model.
The US has grown exponentially because they were embracing progressive ideas faster than others, not because they were cool from the very beginning, and embracing Bitcoin is just their way of doing things.
Just my opinion. Of course, I can be wrong, but that's what I feel right now.
