Bitcoin is only "weighed" in other currencies, as an indicator of how much a Bitcoin is worth against another currency; this does not mean that, if other currencies disappeared, Bitcoin would become worthless.
You can't build a service, a company, or anything with a price that can double within a month.
In 2010, you could buy a pizza for 10k btc. Now, with the same amount of btc you can buy a house, a car and a swimming pool.
In the meantime, you can buy almost the same kind of stuff with 10 k usd.
That's one reason why people trust more USD than BTC.
If fiat disappears, and we need a currency to continue our way of life, then exactly this will happen:
(...)
And if I die tomorrow in a car crash, I would not see the next Olympics Game.
Which is unlikely to happen.
Why would you think about things that will never happen?
Fiat is not gonna to disappear anytime soon.
Your fallacy is in assuming that no one would fight to keep Bitcoin alive, because there's no reason to; Bitcoin is private, does not require a middle man, confirms much faster than credit cards (and at the same time, does not come with the cost of those CC companies), it's locked by distributed computing to never increase its supply, making it perfectly controlled by consensus, does not require an issuer, does not require a government, can be used anywhere on the globe with an Internet connection and a business which accepts it; exactly what is it about the USD that's so attractive?
No, bitcoin does not confirm much faster than credit card. It took me 1 - 3 days to confirm every time I make a transaction without fee. Double spent are unlikely though, but still, you can't say that the transaction is done before the first confirmation...
It took me 10 - 20 seconds to confirm by CC.
Simply because you have doubts, does not mean--in fact, it is completely false to believe--that your PoV is as God's word. It's very unlikely that Bitcoin, if not as a currency, but as a protocol--a technology--isn't going away. It's because of people like me that Bitcoin won't fail, and as I've said in my last post, a currency works only when it's trusted by people; it does not matter if a currency is backed by government, if it's not backed by its people, which has happened more than once in the past, and the USD is no exception.
I don't think that bitcoin will fail, but it is obvious that I trust more fiat than euros, and will keep it this way in the upcoming days.
You might think that bitcoin will succeed, but if you're alone to think that, bitcoin is pointless, useless and worthless.
I don't deny that bitcoin has some advantage. But tell me, honesty: how much money do you have in BTC? And in fiat?
I bet that you have much more fiat than btc, because it is much safer... That's the answer to this thread (title: Why do people trust fiat money?).
People trust fiat money because it is backed by govs.
People trust fiat money because it will remain.
People trust fiat money because its value is almost constant over time (unlike btc).
People trust fiat money because it is accepted everywhere.
People trust fiat money because it is convenient to use.
