Bitcoin has no chance of replacing any fiat, you're out of your fucking mind. What, you think people with actual money are just going to be like, "oh well, I wasn't an early adopter, I guess all those crypto guys will just be the rich from now on!"
There's literally nothing bitcoin has that couldn't be developed by any new cryptocurrency.
8+ years of ground up adoption with no real competition cannot be replicated. The community, network effects, and meme surrounding Bitcoin won't be replicated unless Bitcoin fails. This is more important than you may think.
You can fork Bitcoin code and create all the same attributes except trust in the network. Bitcoin was created specifically to resolve the issues with fiat currency. I can't see the future any better than you can, but I believe that Bitcoin has a much higher chance of doing this than most believe.
Also, I'm not sure you fully appreciate just how antiquated our current monetary system is. If a new technology is 10x better than the previous technology, it disrupts that industry. This happens consistently. I would argue Bitcoin is 10x better than our current international monetary system. Probably more than 10x.
I'd be interested in hearing your rationale here.
I'm not going to write out my whole thesis on why this is true but in a nutshell:
Fiat currency is the root cause of a massive proportion of our current issues. Socially, economically, and politically. I believe it is the root cause of why everything is shitty quality and made in China, why our food sucks, why the family structure is falling apart, etc. Its a long rabbit hole, but that is the conclusion I've come to.
Central banks are responsible for the devaluation of Fiat currencies. History has proven that centralized entities ALWAYS devalue currencies eventually if given control and enough time. All fiat trends to 0.
Ethereum is not decentralized.
Bitcoin is the closest we've ever come to true decentralization.
Bitcoin has won the store of value narrative. That will play out over the next year or two IMO. The next narratives are unit of account and medium of exchange. I believe that this will be resolved on layers 2+ in Bitcoin (see lightning network)
If Bitcoin continues to survive attacks it will eat everything. Gold is first, then the bond market. This is a pretty big IF to be clear. I don't see a good future for us unless we get out of inflationary currencies. The only way to do this is to ensure that no single party is in charge. Only Bitcoin does this.
Bottom line is that there is no way that I can convince anyone to see my point of view. You're gunna have to do the work to figure out why your specific objection isn't as strong as you think. The resources are all out there. Every objection has at least been considered, many refuted. The beauty of this system is that if it works, it will reward the ones that were willing to do the work early to understand WHY it is going to work. We all buy Bitcoin at the price we deserve to buy it at.
Obligatory IMO, DYOR
EDIT: I know that you'll hear and read things that say that Ethereum, or some other coin has real value or is better than Bitcoin in some relevant way. Every other source of information in this world is feeding you bullshit, why would you expect it to be any different here? There is a reason that every Youtube shill is pushing whatever they're pushing rather than talking about Bitcoin. Disinformation is very real here just like it is everywhere else. Don't trust, verify. You do the work in Politics, why wouldn't you with your investments?
