66k is such important mark that it could make or break the complete trend of Bitcoin.
This trend line has been tested 3 times in past and price have risen 24%, 45%, 18% respectively. This time even if its to rise 18% from now, it will bring the price back to ATH.
I am tracking a Bearish WW pattern also in 4HR/Daily charts which points to touching near 55-58k on downside, but the overall move has been tad bit sluggish that I am starting to doubt it.
Lets keep 66k if you are long, as support and go full short under 66k, buy above 67k on upside though and ride till atleast 71-73k
