I don't think USD is going anywhere. It's more likely for crypto, and I don't know which one will take the lead, to replace all currencies around the world. If that happens then crypto can thrive. I don't think this is likely to happen anytime soon though. One of the very important things that still need to be solved (and no that's not energy consumption) is how taxation is going to work. The rich will still find ways to doge taxes, but government can't afford to lose those middle class taxes. Thats what I think anyway.
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
