i don’t leave my car at the lube shop, once i watched the mechanics lock the keys inside the vehicle in the bay next to me. they were able to get it open, but i was glad i stayed in my car, even though it was hot that day. i like to see what they’re doing and know that my keys are with me.
your comment is a moot point. i was saying that it could be private and while it is probably mostly associated with people trying to purchase illegal goods crypto tumblers are a thing so that is something that can anonymize your crypto. also, you can’t pay with cash online so there is a utility of something that can facilitate anonymity in transactions online.
