I know a few street level dealers who have been dealing as their sole income for over a decade. Their experience doesn't expand anywhere beyond "street smarts". Some of them are good at managing money but most are absolutely terrible.
So how is it for online vendors? If they stop; besides the money, are there any skills they can take away out into the real world? I am not looking to become a vendor, just interested in the general idea and vendors mindset.
If they had any sense, they have a small legit business set up anyway to launder away some money- it also provides a fallback in case they take an opsec break or get paranoid or run scam/whatever.
