Why would monetary system collapse?
Because government debt is completely out of control, and rising.
This didn't happen in the last 50 years. The people who are waiting for that to happen - the goldbugs, libertarians, marxists, bitcoin maximalists - they all sound like a doomsday cult.
Indeed, not in the last 50 years and not in your lifetime. But many times throughout history. Ray Dalio is a multi billion dollar hedgefund manager, but also a historian of finance. His analysis of the global situation right now, and the parallels with the 1930s, is quite remarkable and interesting to listen to. I could link it here but you can easily find it if you want to. The current world order was set after WWII with the US dollar as the global reserve currency. There is a need for dollars because petrol was sold in dollars across the globe for many decades. That is ending right now. The entire world is dumping the US dollar. BRICS nations are joining forces. The debt is spiralling out of control. Higher intrest rates will not calm that down. There is a global conflict and there are new rising powers. It's just like 1940 all over again. That also ended in the Weimar hyperinflation.
I don't believe that the great reset is a conspiracy theory. But time will tell
Also, the idea that Bitcoin will benefit from a global economic disaster has been challenged. Inflation is high right now, yet Bitcoin is not in a bull market. It was in a full-swing bear market in the last year when inflation was the largest.
I believe this is mainly because most people are still not convinced that BTC will survive all threats of the banks and the government. Not so much because of inflation. I know quite some people who run to gold because it is more familiar
