$6,921.4 is a 61.8 retrace. I've gone for a bit lower.
You will find all of my bull and bear arguments in my post 24th September "#bitcoin bull bear watch don't get caught out".
Has bitcoin bottomed?
I think we could be about to find out today unless price rises back up, or, need review.
I have boxed in some primary areas of interest to me for comparing recent past, and added below extra photo's for comparison with previous examples.
Here's my latest observation, and below comparing December's example. 50/50 price finds support and my to the moon charts/arguments remain intact. Some of my bearish charts/arguments still have 50/50 chance too.
Here is the daily chart of gold 2.50% 2.09% and bitcoin -4.80% -4.83% . Notice my use of Aroon 1 (blue) 11 (brown). Notice the correlation with Bitcoin -4.80% -4.83% when brown Aroon hits 100. Have boxed in volatility to nearest Blue Aroon at 100. The Aroon is done using the Gold 2.50% 2.09% chart. I've superimposed the brown Aroon on bitcoin -4.80% for better clarity.
Note that move could also be short lived to just one day, or, none at all. 3rd March didn't work well at all. Looks quite good at catching bitcoin -4.80% at point of rebound. All ideas 50/50
