This chart is marked based on the activity of 1-year holders. as you can see, I used RSI for this data. it is a useful indicator to determine accumulation and distribution areas. when the RSI indicator entered the over-low area, many long-term holders sold their bitcoin , and when it entered an overhigh area, it means there are many people which hold their bitcoins for more than a year and are ready for sale.
as you can see, bitcoin is entered the accumulation area now
