In any trading market, at any time in history, no matter where you are, the most important thing you can possess isn’t actually money, or influence, or anything like that. Knowledge — in particular, knowing something before everybody else — is far more valuable. Some traders are willing to go to great lengths to get it before anyone else. In some cases, they’ll apply great ingenuity to the problem – but in others, they’ll use manipulation — hacking into these technologies to gain an unfair advantage, and make a fortune along the way.
