Yesterday's dump was the retest of the $8200 support (previously resistance). In recent weeks, $BTC broke out of two ascending triangles and successfully retested the breakout zone. This parabolic rise also took out big supply points of 2018 (trend reversal price points) at $8400 of July 2018 and $7400 of Sept 2018, which now gives us the pathway to May 2018's run-up to $9900.
