This is very clear for me to about what will happen with time in our future. What has happened to fiat from the above explanation is true and I am not seeing any currency from any country that has not lost value or a little depreciation because of the economic development and changes in the world. This is interesting enough that bitcoin has more advantage
I believe that there is a good chance we could all get into a situation where people could both hold bitcoin and spend bitcoin at the same time. Why did people use gold back in the day to pay for stuff? Gold was valuable and usually got more valuable over course of years as well, but they still used it, because it was life. How could we then make sure that we could still spend it but not lose a lot of money? By going full bitcoin at all times.
I mean if you earn bitcoin and spend bitcoin then you could make sure you end up with more bitcoin then you spend, and that way you would be getting advantage of this, instead of your useless dollars go into waste, you will have bitcoin saving that way. Earn your salary fully in bitcoin, spend 90% of that each month, and you will have bitcoin non-stop.
