This is missing the most important step though, which is to actually launder the money. Concealing the source of the money is only half of the ordeal, making the money seem legitimate is the second, usually considerably trickier bit. If you suddenly receive $100k from a crypto exchange with no trace of how you came to own it, your bank is going to ask you some questions.
If it's a one-time $100k you can just slowly withdraw small portions of it and probably nobody would notice. It depends how much you're trying to launder.
You really think that alerts in banks are that stupid? It doesn't matter if you are sending 100k at once or below some treshold. It will get alerted and spotted anyway. You just need to make transaction look plausible.
I have transferred tons of stuff to my bank over the years (all legal), none of it ever got "alerted" or something I had to describe.
Easy these days with fantasy football being advertised every 30 seconds. There are probably very sophisticated methods already out there running on those frameworks.
