We are going lower. For 12 hours. A day. A week. A handful of months. We don't know. But we are going lower until enough people say "this is a great price." And then we will go higher. For a while. And then we will go lower for a while after that. And then eventually we will go higher and a new upward trend will develop. And then we will go back and forth for a while and then a new bubble will start.
