The white horizontal lines, weather they be solid or dotted are lines from multiple time tested price points. its safe to say that in the event of another downfall that there will be some interaction with these lines, if you look at my BTC day chart you will see what i'm talking about. The bold white dotted line at the bottom is the lowest low we have had in almost 2 years 1/16/17 to be exact. The bold orange ascending line near the bottom of the chart is the bottom line in terms of the lowest trending upward pattern line between two low points on the bottom of the day chart. If BTC somehow breaks through that which is down there at approx 2k, then I would be very surprised. But also excited to just see what was about to go down.
anyhow, use this chart at your own risk. Only you can make decisions for yourself, no matter how gullible you are, it has always and only been your fault and yours alone for all of the things you brought to your perception. Peace, Love, & Light.
