Bitcoin Volatility Hits 18-Month Low Amid Summer Slump
Bitcoin's volatility has dropped significantly in recent months, a rare occurrence for an asset known for its wild price swings. According to a report by VanEck, thirty-day realized volatility has fallen to 27.2% annualized, down from 30.4% the prior month and less than half bitcoin's long-run average of roughly 80%. This calm comes as bitcoin claws back from a June low near $58,500, holding inside a tight $62,265-to-$66,509 band through most of July.
The market's stillness is also reflected in trading activity. Spot volume over the trailing 30 days is down 27% from the prior month, landing in just the 10th percentile of its own history. This summer slowdown is deeper than in either 2024 or 2025, pushing spot volumes down toward levels last seen in the 2023 bear market.
Longtime holders have also started letting go of coins, with bitcoin held for more than a year falling by about 356,000 BTC (-2.9%) over the month. This has pushed the long-term holder share of total supply below 60% for the first time in months.
