It's not becoming; Bitcoin has become one already. That seems unfortunate.
As much as many don't like it, it seems there's no getting away with it. This has become Bitcoin's fate ever since its price attracted supporters more than its technology.
The traditional players in the world of finance are here. They don't share Bitcoin's philosophy. They only believe in the potential of its price, and its ability to improve their revenue.
And now we're slowly getting used to weighing Bitcoin's outlook based on the interest rates decisions of central banks, GDPs, fiat monetary policies, fiscal regulations, and the like.
It doesn't help that even crypto media are constantly publishing articles that focused heavily on price trends vis-à-vis the traditional market. They're pushing the narrative further.
I can see why you take that view, but it does not seem like Bitcoin growing connection with big economic events always means that its main use has been lost.
If you ask me, there is a difference between what moves price of Bitcoin, and what makes Bitcoin valuable to begin with. While interest rates, available cash and government policies may have an impact on demand in short term, they do not change fact that Bitcoin is still ruled by same rules that were in place before the big companies came along. Just because big financial players are trading the network does not mean that it is more controlled centrally.
What is interesting to me is that much of those traditional players have been playing Bitcoin for profit, but they have also been helping to add available cash, systems and public awareness. That might not be beliefs of early buyers, but it has helped Bitcoin get to the scale that it would have been hard to do otherwise.
So maybe question is not so much if Bitcoin is now macro asset, but if an asset can be affected by the traditional financial system without truly changing. I do not believe this debate is at all finished.
