are you sure about Newton? "The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force."
By the way OP is wrong, according to the bitcoin boys on Reddit, it wasn't a buy in, just an exchange moving coins from one address to another one. Fake story... For those who didn't get the Newton reference: Newton played the South Sea bubble and although initially he made money, he decided to jump back into the fracas (aka FOMO) and bought when price went vertical, eventually losing everything. https://www.sovereignman.com/finance/how-isaac-newton-went-flat-broke-chasing-a-stock-bubble-13268/
That happened at 1:18 am, and price stayed in a 200 bucks range for the next 6 hours. The market is either quite deep so selling 4300 BTCs doesn't move it much, or it is just money transfer.
