BTC Head and Sholders Pattern - Looks like a possible top to me.

There is a pretty clear head and shoulders pattern forming on the BTC/USD chart. If the $104,000 support line does not hold, I expect it to go much lower. A lot of BTC related stocks and EFT's also look like they have been in a distribution pattern the past weeks as well. Hold on to your horses.

Based on history a flash crash in and around the Christmas or New Year holiday is most likely because there will be low volume and less people watching their accounts.
