It's not untraceable when your addresses are public so people can send you money, and if you want to exchange it for dollars you have to sell it somewhere - usually people even keep it on a public exchange which completely voids all of the benefits.
Kinda like having a VPN where you publicly advertise what IP you use, what sites you visit, and keep a list of it all on your PC that the police get when they raid your home.

VPN gives you privacy, and crypto is untraceable and cannot be frozen, but only if they are used right.
