Bitcoin OG movement spikes 56% as 1,500 BTC leaves dormant wallets

Long-term Bitcoin holders, often referred to as “OGs,” have sharply increased their transaction activity since May, with data showing the 90-day average of coins moved from wallets dormant for over five years now reaching 1,500 BTC. This trend comes as Bitcoin’s price trades in a tight range near $80,000, showing little momentum to break above this threshold.

Bitcoin OG transaction activity jumps

According to new research from CryptoQuant’s analyst Darkfost, veteran Bitcoin holders more than doubled their average spending activity compared to June, when the measure dropped to 962 BTC—its lowest in almost two years. This was also the first time since November 2024 that the figure fell below 1,000 BTC.

The 90-day moving average is used for this metric instead of daily readings, helping to reduce noise from large, individual transactions and giving a clearer view of shifts within the longstanding holder group.

Darkfost noted that “OG Bitcoin holder activity has intensified during this consolidation phase. The 90-day moving average of spent UTXOs from holders who have held BTC for more than five years just climbed to 1,500 BTC.”

Bitcoin traded at $79,901 at the time of reporting, up about 0.33% in the previous 24 hours, but continued to experience sharp swings between $78,723 and $81,370. The price remained pinned below $80,000 despite this increased on-chain activity.
