It's not untraceable, but it's way more anonymous for routine purchases than CC. Also with all the nonsense the CC companies are pulling lately, it's a nice example of why de-centralized, unbanked fiat has real value. Personally I use it for search engine subscriptions and paying VPN fees with at least a layer of "hey, you can't sell my demographic data or send me junk mail" privacy. Also if you want to send money to someone without using venmo type garbage, it's super easy and flexible even if you don't have the same type of crypto as the person you are sending to. It's huge for sending money internationally as there are big fees associated with international money brokers when involving traditional fiat.
The mantra of crypto as a scam is wrong. It's just seriously overvalued and has been turned into scam as an investment commodity. The technology itself, at least modern scalable versions that don't require AI level nuclear power plants to scale, is not flawed. The fact that the archiac unscalable bitcoin prototype is still the most valued is a great example of the mismatch between real world value and the fucked up crypto marketplace.
