Every day there is more and more people accepting btc. At some point in future, why not. But we can't do it now.
Entire world should accept BTC as a currency, so your suggestion gets real.
I believe in 20-30 years that could happen.
( I might be wrong as well, since I'm just guessing )
Why not!?
Who has to begin?
I'm hoping you to sell, not doing this to make buy.
You begin inserting the idea,
time is relative. 20-30 years? Do you need this time? We ARE in the new era, now!
A natural process of substitution is acting. Is a law, Good currency drive away the bad one!
At present moment the only strength of fiat is because it is fiat.
The benefits of fiat is that you know that people will accept.
In this era fiat currencies have a problem, that is fiat.
