The chart pattern that captures price action of Bitcoin on its 6 hour timeframe from March 18, 2018 to present date is a symmetrical triangle.
Price successfully closing outside of the triangle at ~$6,608.50 implies more upside momentum for Bitcoin, albeit current correction after breakout from the chart pattern.
Bitcoin closing back below ~$6,215.70 would possibly trigger more selling. A logarithmic scale was used in this Bitcoin analysis, and therefore requires an arithmetic scale for any physical measurements using the width of the pattern, which is a great way to estimate the minimum termination price level for Bitcoin.
