Rachel Dashiell dials up the chart of Bitcoin (/BTC) to look at the "velocity of this selloff" occurring this week. She says there's been "a lot of damage" but says there could be a possible cup and handle pattern forming. She says $70k is a level to watch in the near term. On a longer-term 5-year chart, Rachel shows the significance of the $65k level of support and how its relative strength indicator (RSI) has fallen to oversold levels.
