1-  People buy Bitcoin because it makes them profit from it

2-  Bitcoin makes profit because it makes people buy it


It's a circular argument, and creates a perfect closed system, no other "product" can make it, in the center there is greed moving this perfect circle


---------------

And why it's impossible to copy bitcoin's proof of work, meaning that only bitcoin is proof of work is valid:

If many people wanted to buy another PoW coin instead of Bitcoin, the price of Bitcoin would rise, meaning it would generate more profit, which would make people buy only Bitcoin. Therefore, it is not possible for people to buy another
proof of work coin instead of Bitcoin because this would make Bitcoin's price increase generating more profit, which would prevent competition.
In a normal company, competition forces companies to lower prices. In Bitcoin, the logic is inverse, it raises the price and prevents competition from emerging, which makes proof of work impossible to copy.


if this logic is invalid, please correct me if i'm wrong thx
