The problem is that dollar has roots deep inside, so deep that some people and countries can't even imagine. The whole world economy depends on the USD, we measure everything in USD because the internet and modern world connects us worldwide and America with English language is a global leader in economy, military and so on. This is something that no one can stop.
While it's true that dollar has an symbiotic relationship with countries and America enormously benefits via it by importing its own inflation and exporting one's economic growth, the problem is that you can't get rid of it.
As I see lately, countries like Russia and China are increasing their gold reserves but I don't get one thing, America, Germany and western countries have the highest gold reserves, so, what's the point? Still no one can escape from these claws.
The chances of more countries using their useless fiat in order to settle trades?
Just as much as every single one of you denying a Bitcoin payment and choosing to be paid in PooGrow, which
is an actual coin, btw!
This is probably personal. Please, explain, what's wrong with Ethereum? What's wrong with Monero? And please explain, why don't we want to increase block size or implement lighting network or any other solution? Why are all of you so futuristic and so conservative at the same time? Futuristic because cryptocurrencies are future and you support it but conservative because you can't or don't want to understand that the current bitcoin infrastructure isn't perfect and needs change, if it won't change, people will change their choice.
