It is not scary to me but funny. I think in terms of fiat, it could be the currency of high volume in exchange. Like the foreign currency such as US$, pounds and Euro. Many times I have heard of money laundering, it is always in those currencies and not in local currency because the value is small in exchange for the above currencies. Politicians take out money or embezzle public money by converting plenty of the local currency to few currencies with high exchange rate. However I have not heard of money laundering on cryptocurrency except scamming and that is quite different from money laundering.
