According to reports, Kraken recently released a report called "Shocktober" that the 1-year recovery of BTC supply provides a detailed view of long-term holders' supply activities. This indicator shows the number of tokens that became active after being dormant within a specified time frame. A small amount of Bitcoin re-enters circulation from the fourth quarter of 2020 to the first half of 2021. BTC's HODL Waves indicator reflects the percentage of BTC's circulating supply that has not moved within a certain period. The data shows that long-term holders did not sell during the weak September period or sell during the October intense period.
