I always think it's hilarious that people who call themselves Bitcoin enthusiasts will say things like "No one wants to live in a country where bitcoin has become vital for payments", when the original Bitcoin paper calls it "A Peer-to-Peer Electronic Cash System" and the introduction quite clearly suggests that it would be better for people if they used Bitcoin to replace trust with cryptography. Please just read the first two paragraphs: https://bitcoin.org/bitcoin.pdf

(Or actually, read the whole thing, it's interesting, but it's obvious that the experiment really didn't turn out the way it was planned)

You see money was one of the first distributed systems, it transcended languages and flags, the protocol was deployed everywhere. But this protocol of value exchange always had issues with trust, related to the double spending problem so it always required a third party. Gold is almost perfect because it is rare and recognizeable, but gold can be faked and is too heavy to carry around in large amounts also violence can come from gold and violence is a big no no for the cypherpunks. So for our traditional protocol to work we invented money printers that we trust to print our money (Banks) and monitor it for tax purposes. But now maybe for the first time in the world it is possible to have a P2P system of value exchange, no banks, kings or even governments required, the only requirement is a cpu. The new protocol offers new ways to structure our economy, it makes old ways obsolete but it has its own set of problems. Is the new protocol good or is it bad? I say it is too early to answer this, but I also think crypto-coins should be given a chance, it is good that people are starting to use this protocol it gives us real-life data to compare its pros and cons against our traditional protocol.

In many cases it is true, but the one legitimate use case is helping out in countries where monetary freedom is restricted. When the state forbids you to sell a currency that's permanently losing value due to unchecked inflation, being able to work for any appreciating coin or even a stablecoin is benefitial to society.

I wish I could filter out every "Bitcoin dumb LOL" reply that inevitably appears in the comments. We get it, we've heard all the jokes before, thank you.
