Many people love them both. But most people use Dollar. But many people use also Bitcoin and that is very good. I hope that more people will use Bitcoin.
But it is hard to learn some new people how Bitcoin works. The older generation doesnt even know what Bitcoin is.
I think bitcoin users only 1% of the total world population, while users fiat is spanning the globe.
how bitcoin can win against fiat?
Well, fiat encompasses the entire globe at this point, the only way it is expanding is through people being born.
To compete against fiat, there has to be either massive distrust or a massive collapse with the financial system coupled with Bitcoin becoming a huge powerhouse that can replace fiat in a reliable way. this not only makes those who currently own bitcoin quite wealthy, but it also demonstrates the versatility of Bitcoin and how a decentralised system is far better.
