There is/will be a learning curve before something like this happens on a broad scale. Mass adoption comes with mass ignorance, and those unfamiliar with the technology drag with them what they know and are familiar with, which is centralized.

Providing options/examples of any known decentralized exchanges is valuable, obviously coming with any appropriate caveats. I will read the comments in hopes of finding a lead.

I'm in the process of overcoming my own ignorance on the crypto world.

Edited to add: A perfect example of my own damn ignorance, I ticked the upvote post when I made this comment, I only just discovered it today, first time trying to use it, and I thought it would upvote this post, not my comment. When I didn't see the post upvoted, I realized it must have upvoted my comment. Um, yeah, another lesson learned. ~sigh
