With the massive plunge recently, BTC pushed through its main support line that was keeping it "parabolic". This being said, BTC must find a new support line for this next wave, and there's no clear contenders. 2015-2017 shows a line that BTC continually beat on.
BTC's last recovery followed the Gann Fan tool quite well. I've looked for similarities between the 2 market cycles and applied the Fan appropriately. Here's how I see BTC crawling out of this bear market. Looks like we'll have a couple years to accumulate, and this scenario is on the more bullish side of my analysis's.
