The launch of a Bitcoin exchange-traded fund (ETF) in the United States had a direct impact on the reserves of Bitcoin miners, with more than $1 billion in Bitcoin flowing from miner wallets to exchanges within the initial 48 hours of trading.
According to the latest Bitfinex Alpha market report, the second day of Bitcoin ETF trading on January 12 witnessed a significant surge in funds moving from Bitcoin miners to exchanges. Data from Glassnode revealed that over $1 billion worth of Bitcoin was transferred from miner-affiliated wallets to exchanges on that day, marking a six-year high in miner outflows.
On February 1, another substantial amount of BTC was withdrawn from miner wallets, with approximately 13,500 BTC being sent to exchanges. However, on February 2, about 10,000 BTC was returned to miner wallets, indicating possible wallet rebalancing by specific mining companies. The net outflow of 3,500 BTC on that single day was the highest recorded value for this metric since May 2023, as noted by Bitfinex analysts.
Since the approval of the Bitcoin ETF in the U.S., on-chain data reflecting Bitcoin flows in miners’ wallets has predominantly shown negative trends. According to CryptoQuant data, net miner outflows have been estimated at around 10,200 BTC. Several factors influence the flow of Bitcoin from miners’ wallets, including the need for operational liquidity, responses to market conditions, and adjustments following the ETF approval. Additionally, some miners may be capitalizing on the price surge leading up to the ETF's approval by liquidating holdings.
While miners have been observed moving Bitcoin from their wallets following the ETF approval, on-chain data suggests that long-term Bitcoin investors are holding onto their assets and are reluctant to sell at current market prices. Analysts highlighted a decline in the last active supply of Bitcoin on one- and two-year timeframes, particularly related to the Grayscale Bitcoin Trust, where dormant Bitcoin holdings have been activated or exchanged for other Bitcoin ETFs. These changes in older Bitcoin supply serve as indicators of market behavior, reflecting shifts in investor sentiment and strategies in response to ETF developments or evolving market conditions.
Despite fluctuations in short-term movements, analysts believe that the majority of Bitcoin supply remains securely held, reflecting a continued belief among long-term investors in the future appreciation of Bitcoin.
