Just because everyone is in on the scam, doesn't make it not a scam. It just makes it a systemic scam.
Why are you talking about usdt? The price of usdt has always been the same as usd and no one is forced to use usdt. This seems irrelevant.
So don't use it.
This isn't a bubble, by this point it is a market for middleman-resistant bookkeeping. It'll be the same as gold, we've had people claiming gold is worthless for all of recorded history and it keeps on going.
It's not a bubble it's a set of scams whose primary value is in allowing bad actors be they oppressive governments or criminal groups to move money around bypassing embargoes and bans. On top of that we also get a new scam bubble every little bit so that we can point and say "see that one isn't a scam" until it turns out it is, or its being used to send money to north Korea or Iran or whatever.
It's not one scam it's a series of scams. It's not useless it also allows large scale financial crimes. It's amazing!
This is a strawman. There is abundant evidence that crytpo was being treated as a get rich scheme, and the lack of sustainable use cases are why the sector has contracted so much.
I'm sincerely asking. That appears to me the endpoint of the argument you make here. I might be wrong in my interpretation or conclusion, so please do correct any inaccuracies or leaps you find in my post.
I am not a fan of cryptocurrency, because I think it is stupid. But I am a fan of (actually) anonymous and privacy preserving currencies. So I can continue to not harm or victimize others, but acquire the molecules that make me the most functional.
This is certainly an ideal that libertarians hold, though I do not claim myself or my views as being particularly libertarian.
More importantly, the vast majority of anonymous transactions occur via ownership secrecy havens. Quadrillions are held and transferred in offshore havens like Nevis, which has beneficiary and ownership secrecy baked into their constitution. Monero democratizes transaction secrecy, allowing the middle class to have the same level of financial privacy that criminal organizations attain regularly by incorporating in an offshore haven and hiring the appropriate lawyers. If transaction secrecy were a legitimate concern of yours, you would be eliminating it where it actually happens and facilitates crime first.
