There are many indicators that help to identify entry/exit points for Bitcoin. We have written many posts for that purpose.
Another robust indicator for this purpose could be Inflection Points of Maximal Mean Age. Below graph, taken from Santiment, shows the same:
In above graph - the inflection points of Stack mean doller age are very good entry/exit points. If Age reduces then it is entry point (shown with green line) and if age increases then it is exit point (shown with red line).
Now we will wait for stack mean dollar age curve to starts moving up before we call the exit. Obviously we will corroborate it with other indicators as discussed in our post My outlook on current state of Crypto Market
