Re: What will happen if we use a one currency only?

[Edited to make it more understandable question]
What if all nation use only a one currency or one global currency?, What will happen to our world?, What is the effect of every nation's or every country economy?, It can make people's unite each other?Any opinion. Cheesy

for this to happen one world currency
there is going to be one leader worldwide
or else it would war and chaos
but its frightening to see that one world currency and one leader above all

I guess that will somewhat signal the beginning of the end of the world and so I hope Bitcoin will not turn out to be that one currency per the current global acceptance rate.

For sure no one would accept this kind of thing because we come from different cultures and we have different beliefs. For sure, as humans, we tend to believe who we are closely related to like, for example, the religion. That could divide us already, so not expecting to be united in a way that we all have one leader all over the world.

So, if you want to have a currency for international, you only can use the most popular currency because no country wants to apply a currency from other countries or a currency like crypto to the country's economy.
