> what does owning a bank do that owning a (for example) car wash or funeral home or laser tag venue doesn’t? Is it purely a scale thing? All three of those are very much focusing on _cash_ transactions. It would be difficult for any of those to hide wire fraud. As all of those are references to TV shows revolving around drugs. Drug sales are usually done in cash. If you have over tens of thousands in illicit cash, you need a cash business to mix those transactions in. Clean cash + dirty cash = plausibly clean money. Did your laser tag place really take in 50k in cash a week? That is a harder question to prove than you don't work, where are you getting 25k a week from? You'll need good book keeping. However crypto investments don't have any cash transactions. You need to make and recieve wire transactions. These transitions are likely legal but still questionable, and most banks will terminate you if you have questionable transactions. Owning the bank means you don't need to answer a lot of these questions like "where did this money come from?"
