Sadly, we ALL should expect this. It's happened over and over and over throughout history - 100's, 1000's of years. Read the book, "Manias, Panics, and Crashes: A History of Financial Crises"

In a way, I'm glad Bitcoin is just on a steady climb. When this thing busts everything is going to suffer - but 1 bitcoin will still be 1 bitcoin, that we know. Just be sure you have a couple years of cash to ride through the storm. Where the hell you keep that cash I have no idea! Maybe under the bed! lol
