Evo Market used to have this guy that'd sell real money in the mail, for bitcoins. It took me a second to figure out why someone would pay $125 for a hundred dollar bill, when there were fifty fake twenties for two hundred... DarkNet cashing out.
I've looked for a similar service and I'm not seeing any; is that due to lack of interest, lack of faith?
If there's interest, I'm thinking about signing up to do that. It'd be too easy to put some gloves on and mail money to people. Small margins, sure, but I'd be able to slowly fundraise for my little projects.
I believe /u/Pelican_vendor was doing something like that as well. He posted %s but i don't remeber off hand
