Or, make all that $$$ yourself by starting an ad exchange for cannabis-related websites. Beware: banking will be really hard. You need to accept money from ad buyers, and forward most of it to ad sellers. Most of the ad buyers are doing things that are illegal under federal law, so banks won't deal with them. They might have suitcases full of cash, but it's hard for them or you to turn that into ACH deposits for the ad sellers. That problem may be solvable, just a heads up that it won't be easy.
