@garbados I've filed cryptocurrencies in the same bucket as hydroponics, vaping, cell-phone repair, and head shops: there's lilely something useful in there but you have to dig past the dudebros and douchebags in order to find the nuggets of good stuff. And a lot of them are just clueless folks trying to make a quick buck before the bubble fades.
When Michigan "legalized" medical marijuana there were an explosion of hydroponics stores here. One of them was next to a coffeeshop that I frequented. And the folks there were predictably dude-bros who felt it necessary to paste a copy of the constitution underneath the picture of Ron Paul.
There's completely legit places (my bro-in-law grew veggies in his house). But a few of them seemed like flames for moths
