To fight against the control of USD thus create an anchor for people all around the global, or to make transactions apparent in cyber world, Bitcoin was coined by Satoshi(the second one is more valid).
Will the day come when everyone uses Bitcoin in daily payment(supposing new tech is applied to avoid high gas fee) and thus fiat gets abandoned? Or it won't because the amount of Bitcoin is set and all Bitcin is practically manipulated by capitalists...
Obviously , it's nearly impossible for Bitcoin to realize permant and global circulation due to its high price and scarcity, which renders it harder to take the place of fiat but it sounds that ETH is likely to be an anchor and a tool for daily use alike, surpassing BTC is feasible.
They say, if a country is at war or in upheaval, buying Bitcoin is not wise for its high volatility and USD is a better choice.
How do you think

It has always been a debate if bitcoin can even replace fiat but in my opinion, it's too far from happening considering many factors. With regards to Ethereum surpassing Bitcoin, you should know how impossible that can happen. Just take a look at the price gap of the two, even though ETH has always been next to bitcoin, the price gap is so far. Fiat currencies is already part of the tradition in all parts of the world, regardless of having technology innovating over the years, a digital currency would take up a lot of adjustments before it can be seen feasible.
