Maybe I'm not very knowledgable, but even Monero seems sketchy to me. I've clicked into what I thought were blogs about privacy that ended up being sites that exist only to promote Monero, once you look into them. That and the way certain accounts will do nothing but praise Monero just seems very greasy to me. I also wonder how it solves some of the other problems inherent to crypto, such as the environmental concerns.

For things like drugs like the person mentioned below, I don't think I'd trust someone who didn't just use cash.
