Rome

You ignored how it ended.

I was talking about the economy of the EASTERN Roman Empire. As for that's ending, while I didn't give a lot of details, I explicitly told you how it ended, by the Bankster's hording gold. It was robust enough that it remained stable and thriving through a thousand years of direct attacks by the Banksters before it succumbed.

How did bankers hoard all the gold? Because people gave it to them

I mean... sorta? But

A) they gave it to them because the bankers owned all the stores where one buys stuff, just like today

B) they owned all the gold mines, which means any new influx of gold went straight into their coffers. Most BtC was mined by the CCP, which is an organization created and controlled by Rockefeller/Rothschild. All current productive mining is being controlled by corporations that are again, owned by Rockefeller/Rothschild and their ilk, one great big monopoly.

Now, I realize it may seem to be more widely distributed at the moment, but ownership is still pretty highly concentrated in the Corporate Monopoly that exists (see link above), and the "anonymous" distribution is almost certainly held primarily by the same entity, because they literally own all the money in the world.

If you think BtC isn't being completely controlled by the people who own quite literally all the money in the world, you are either naive, or lying. They created it, they mined it all, and it can be shown that it is mostly held by corporate interests (again, see the link above that shows there is only one single corporation in the world).
