In 2011, 2013, and 2016, the market was bullish during Christmas week. In 2012 and 2015, the market was sideways. I don't agree with the conclusion that the crypto markets always dump at this time.
Whenever people start seeing patterns like this, the patterns fail. That's no surprise given the lack of historical data and unpredictability of markets.
This is a congestion zone in a ranging market so my hopes aren't high for huge fireworks (in either direction) this week. My overall bias is still leaning bullish. Targets in the $8K-$9K area seem possible in the next couple weeks.
