It is inevitable.
The nature of money is to have one form of account. It will eventually be ∞/21,000,000
The smallest countries with the weakest FIAT will hyperinflation first vs BTC. They have 3 options:
1. Use a substitute FIAT such as USD, Euro, ect. If you don't own the money printer the guys that do get to steal from. Your country and people through inflation endlessly leading to stagnation and an impoverished nation.
2. Try to start FIAT over from scratch. Always leads to impoverished country for decades and finacial ruin.
3. Move to a bitcoin standard. The earlier they do this the better it is for their country. International game theory ensues.
Plus as BTC becomes more ubiquitous across the world the people will take option 1 & 2 off the table for their governments as their FIAT fails.
It is a matter of time before all FIAT fails vs BTC and the entire wealth of the world is denomited in BTC.
I'm not bullish or bearish. This is inevitable. It is only the time frame that is up for reasonable debate.
