Money laundering is such a bullshit term... much like "terrorism"... or "thoughcrime"...
It is very dangerous that we let the government decide what "clean money" is, and what "dirty money" is,
because ofcourse money doesn't stink. Money is just numbers.
Government wants to control everything we do, and wants to restrict our possibilities of what we are allowed to do. Therefor they invent bullshit terms like money laundering.

Jon Matonis from bitpay said it best in this article:

Money Laundering is financial thoughtcrime.

Thoughtcrime... you are not allowed to think stuff.
Political correctness... you are not allowed to say stuff.
Money laundering.... you are not allowed to use your money the way you like.

Wake up people, what happened to "protection from confiscation" against corrupt governments?
This was a notion that has always been important since the dawn of history. It is never illegal to secure yourself against the people who want to damage you.
It doesn't matter if those people have funny costumes and badges and call themselves government. That's just theater to make you think they have somekind of "god given" authority over you.
