Bitcoin wallet cohorts have collectively shifted to net selling for the first time since early June, with whales holding more than 1,000 BTC leading the move. Glassnode’s Accumulation Trend Score stands at 0.37, with readings near 0 indicating selling pressure. Bitcoin fell back below $80,000 after meeting resistance at the key $83,000 level. It is also facing resistance near the 50-week moving average at approximately $79,687, while a potential 50-day moving average crossover above the 200-day moving average as early as Tuesday could form a golden cross.
