What money laundering means?

The definition of money laundering is "to conceal the origins of illegally obtaining money".

Explanation:

Most of the time the way in which the money is concealed is by stating it was a foreign bank transfer/business or that they recieved [earned] the money through legitimate ways.

So they basically obtain money illegally and hide/lie where they got it from.

it's actually a very difficult task, due to not many people can make 2 million dollars in 2 years. besides that, to the not-so-realistic ideas, you can create a business. it could be practically anything, but make it into a business that isn't that known yet, you get me? also, lets not forget about stock market. that's where all the good stuff happens. use investments at the beginning and begin to raise up your business or whatever you're going to do. as this is a very non-realistic idea, it's still worth the shot!
