Using Localbitcoins. Due to the incredibly high crime (thanks to the fucking narco-government) not too many are willing to risk their lives in a meeting with a stranger.
What crime risk can be if you meet in the public place in daytime?! The only one I can imagine is the stranger will be a cop
If this is the edge of hyperinflation, no cop could feed or support his family on the salary, so they would be on the take from necessity. That was the reason the cops recently went on strike.
Ergo, nothing to worry about from cops. You'd want to get one or a couple to hang out where the local transfers were made. Give them a steady income.
What nobody will be understanding is how rapidly the onset of an inflation like this will be. If I was down there, I'd likely go get a car or two on fixed interest loan.
I am not advocating illegal activity, this is all well understood and has been the subject of numerous books.
