Throughout BTC history, the established support trend line from Aug '15 has proven to be a very important one for the Bulls. For 4 years now, we've seen multiple retests and Bull continuation moves started from it . The run up to 14K in 2019 was certainly a good example of the strong support, given that BTC just retraced 84+% from ATH (20K).
Now as we decline once again this year from the June '14K high, it remains to be seen if this long running TL support will behave as a launch pad for future growth. Either way, the pitchforks should act as decent guide to where BTC price will range and test going into the next couple years.
