You know what's also fake? The pieces of paper in my wallet with pictures of dead people on them. All financial value is based on shared delusions. It's a matter of picking a story you like most.
All order books would collapse (including BTC, Gold, Silver, and yes, even USD) if the large holders dump. I imagine China may do this some day.
Sure, everything is fake, just pick your horse, make a bet and see where it goes. Most people don't like volatility of crypto and that is why they will never touch it.
