After watching most of this a couple of interesting things. The credit union that does bank the cannabis industry doesn't keep the cash on hand. LOL. To risky. I thought the whole reason to use a bank was for safety and if it's to risky for them might as well take chances on your own. Just my opinion of course.
2nd thing is banks work very closely with Law enforcement.
3rd is that every MJ business is still in conflict with fed laws. It definitely creates some states rights versus Fed laws problems.
Easy fix. Feds drop their BS prohibition on marijuana and let individual states make their own determination on the cannabis industry. I gave that up after high school when I had to get a job. But the old battle cry still rings true for me. " Man makes booze, God makes grass. Now who do you trust?"
Bet the bankers would be climbing all over themselves to get a piece of the action.
