The bitcoin rally technically ended with the decisive break of the $422 swing low on Saturday. First we saw prices crash through this level on OKCoin and other Chinese exchanges. The U.S. dollar exchanges like Bitfinex and BTC-E took a bit longer to break the level but soon enough they joined in the selling as well. On the chart below we can see that on OKCoin we hit a low of $393.22 on Saturday afternoon.
