About 81% of Bitcoin's circulating supply, or roughly 16.3 million BTC, has not moved for at least six months, leaving about 3.7 million BTC in the active float. The Bitcoin Inter-exchange Flow Pulse has also turned bullish after forming a golden cross with its 90-day moving average, with BTC inflows into derivatives exchanges rising above that average. The indicator had remained bearish after Sept. 12, although Bitcoin continued advancing during that period. Long-term holders have added more than 3 million BTC since 2020, while spot Bitcoin ETFs recorded $134.51 million in net inflows and weekly inflows approached $2.6 billion. Bitcoin traded around $83,970 after recently approaching $87,385, with significant sell orders between $85,122 and $87,000 and buy orders between $82,000 and $83,500. The signals indicate reduced coin mobility and improving derivatives flows, but neither guarantees a further rally.
