I gained knowledge about economics and trading mainly after being introduced to Bitcoin, later I learned that Bitcoin is not just for trading, it is a kind of economy power that is created through decentralized design.
It was originally designed as a payment system, remember the Bitcoin Pizza day?

So today there are countries that looks into Bitcoin as their national reserve so it is what it is, as you have said, it could be a economy power soon.
However, it will still remain as what Satoshi wanted it to be despite how it evolved in just short amount of time.
