Monero, DASH, Zcash and plenty more are great examples.

You're not understanding the difference here still, it appears.

Bill Gates cares nothing of $20k, right? The reality is, that's most people's bank account. Hell, most people, in all actuality, have far less than that number in their bank account. For Bill to care at all about other avenues of value exchange, they have to offer him some kind of utility. The inconvenience alone of washing numbers that soothe his appetite, closer to the range of millions, are kept close track of by the crypto community at large. The people with large holdings like this are called whales. These whales and their exchanges are monitored closely. Most people do this so that they can profit off of the instincts of people that have already done well enough for themselves.

Bill Gates unquestionably would be audited under this system. Anyone with that kind of money would never involve that many people in their schemes, just to wash money in this way. Look, even cash itself has this same pitfall - this is why Gates was a horrible example - this is why the trope of the briefcase is so pervasive in theater: you see a huge briefcase or two, you know people are moving big money around. Hell, Walter White had to keep all of his cash in a shipping container.

I'm sorry my friend, but it's hard to take you seriously. I'm trying to help you guys here. It's unfortunate that the extent of your cognizance is a bunch of "what if"s. Maybe, instead of pointing out low hanging fruit, try asking me some questions...
