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

for now we can see many people who use ethereum and bitcoin in their transactions, but the transactions are made online not directly. from there we can see that the future of crypto is getting better and everyone tends to use it in their transactions. maybe, for the next few years Crypto will be used as a legal exchange tool online, able to pay for shopping online using Ethereum, btcoin or other currencies. This is very interesting in my opinion if there are special regulations from the governments of all countries
