I'm still surprised that weed shops are having a hard time finding places to operate as banks for them. I would have expected for them to be a lot more support from at least a few people somewhere.
They might be able to operate using Bitcoin, but during market trends like the ones we're experiencing it might be hard for them to find confidence in maintaining any sort of serious stockpile of Bitcoin without selling off fairly quickly and ending up with a bunch of fiat held in an exchange.
Either way, they should look into it. It solves a lot of their financial security issues pretty quickly.
