Hey the circumstances were different when it touched 20k, and prices went down due to heavy selling which is normally expected, what one didn't anticipate prices would crash suddenly so much. Another reason of bitcoins crashing was the influx of non stop fud, and false misleading headlines in the media. In the present day bitcoins prices are rallying upwards cause people are buying it, however no one has termed it as a rally yet it's need to sustain itself before we can term it as a rally.
