The only thing that really happened was that some folks who think bitcoin is just another market that you use Wall Street strategies for got their clocks cleaned.
The only people selling at $160 and $155 were wonks and day-traders that had stuck in stop-loss orders. Now when they wake up in the morning, they can look at their balances, and then climb back into bed and cry into their pillows because they got their pockets picked.
Bitcoin trading is not Wall Street, and if you try that crap eventually you will get eaten.
