This is the weekly chart for Bitcoin. The chart has the Cash In/Cash out Report applied and set to 12. This means we are looking at 12 weeks of the sum of cash into and out of the market. There has been very little buying on BTC lately. However, between $19,000 to $20,000 there is a very valid support being tested. There was a strong peak in price back in late December 2017. Pay attention to price action in this price range and act accordingly.
