Money laundering is never a crime. They made it a "crime" because they are too bad at catching people for real crimes such as theft.
OK, I will change my stance to: money laundering is currently a crime in many/most countries however bitcoin mixing is not money laundering. Good enough?
Almost, but not quite. How about "money laundering has been declared a crime by the scribbles of politicians in many/most countries". The distinction matters, because what a man who thinks he has the authority to define right/wrong says versus actual reality is very different. In some countries chewing gum has been declared a crime by politicians. Has morality changed? Is chewing gum somehow now an immoral activity worthy of punishment?
Money "laundering" in and of itself is not a crime; however laundering stolen money is, and knowingly aiding and abetting someone who is trying to launder stolen money should be punished.
Money laundering is never a crime. They made it a "crime" because they are too bad at catching people for real crimes such as theft.
The law defines what's "crime". Money laundering is a crime in most countries. You can argue all you want "you made it crime because you are not good at catching people" in the court, all you want, but that kind of defense won't stand a chance.
The "law" is comprised of arbitrary scribbles of men who think they have the right to tell YOU what is right and what is wrong. Don't fall into the trap of accepting what politicians say as absolute truth. Their "law" is flawed. If you're not hurting anyone, you're not committing a crime.
Offtopic : In most countries, governments are voted in by the people, and the majority keep them there. They then make the laws, based on what the majority want. If you are in the minority, and you did not vote for them, you simply outnumbered and they will tell you what to do.
Let's just forget about all this politics, and concentrate on what is right and what is wrong.
1. It was wrong, when the hacker entered his private dropbox. {Did he give him permission?}
2. It was wrong to monitor his actions and to time his attack {Invasion of privacy} ---> The very thing, you guys are saying mixer services are protecting. {your privacy}
3. It was wrong when the "coins" was taken from his wallet, with a stolen password. {That is theft}
4. It was wrong when a legit service was used to mix coins, in a attempt to "clean" them.
5. It was wrong to rub in the salt, into a open wound. {Emails to the victim, keeping him hostage, to get his own property back}
Yes Klee made mistakes and we learn through our mistakes. {Nobody is perfect} A Ethical {White hat} hacker would exploit vulnrabilities and inform the entity without claiming "bounty".
This is obviously not a white hat hacker, you dealing with.
Klee if I were you, try to establish contact with this person, and negotiate a return of your money, with a offer for a reward. {Paying for the lesson, you have learned}
This thread and the other thread is just harming your cause. {Screaming / negative comments from people not involved / threats will have negative consequences in my opinion}
Pay a team of legitimate hackers and forensic experts to track him/her down and deal with this in the courts or settle out of court, to save you even more stress.
And get some sleep. {You need a clear head, to make the right decisions}
Good luck, we will stand behind, what is right in this world.
