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

There is an impact from every development made by bitcoin, and Ethereum, the different portion they targeted at the beginning of its emergence, Bitcoin at the time of its emergence even had a price that was nothing more than a meal in Italy, but over time, they were able to prove that process determination cannot separated from their own hard work, while Ethereum has differences with bitcoin, Ethereum is likely to be a more rational everyday use tool than bitcoin, given the lack of scarcity like bitcoin, and I agree with your statement, that buying USD is the best option in times of volatility high for countries at war.
