Thanks to low volume and the advent of Bitmex 100x leverage margin trading it's now possible for whales to pump and dump Bitcoin, which is why we've been seeing 5% up/down swings over the past week. Here's an idea of how to take advantage of a potential 5% upswing.
Why is the price moving up and down ~5% ? The answer simple. Because you only need 4% swings to liquidate people who are trading with 25x leverage. The point is to liquidate shorts/longs with high leverage.
