In 2017 you can see the exact point where BTC began to tank back into bear territory, directly after a massive run up which was almost entirely vertical which usually indicates a sharp downturn incoming when it finally breaks. I believe BTC will reach new ATH's before we see this again. We're already on a fast and furious road to new ATH's for BTC so I will be watching closely soon. Last bull market we only took 18 days to get to the peak.
