I have looked into this extensively. If you buy gold with it, or anything really, from a reputable dealer, large cash transactions are not going to happen. Just like you can't go to a car dealership and buy a vette with a suitcase full of 100s. Has to be a bank trail. If you have a lot of crypto to move to a bank account, you will need an answer as to where it came from because after a small amount agencies will inquire. That means you need a business front to launder thru, or a way to funnel the crypto to dollars by other means than a bank account. General rule of thumb, if you have to move 10k or more, dont use a bank account if it is dirty money. If it is clean you have no worries.
