Pi cycle top indicator has
predicted the previous tops with good accuracy. April 2013 was a bit messed up but December 2013 and December 2017 looked crazy accurate.
https://www.lookintobitcoin.com/charts/pi-cycle-top-indicator/Orange line is 111 day moving average (111DMA), green line is a multiple of 350 day moving average (350DMA x 2).
When both lines crossed in the past, it showed we reached the top or close to it.
Look where we are in March 2021
both lines look close, but let's zoom in
Both lines are still quite far from crossing, I find it very interesting to compare with
September - December 2017:
You can see both lines were getting close in that period but this is the moment Bitcoin skyrocketted. Also be very careful, this is when it's time to sell, or at least do not buy when this happens. If we follow the same patterns as 2017 we are 2 or 3 months away from the top of the bubble.
