According to the source, over 32,000 BTC worth nearly $4B moved on-chain from wallets dormant for 3–5 years, marking the largest such transfer of 2025. Based on the source's data, the update does not specify whether these coins were sent to exchanges, so no direct inference about imminent sell pressure can be drawn solely from this movement. Based on the source's data, traders should await follow-up evidence such as exchange inflows and order-book shifts before positioning for potential BTC volatility.

According to @OnchainLens, a dormant Bitcoin whale holding 691 BTC woke up after 12.5 years and transferred 100 BTC worth approximately $12.49M into two different wallets, highlighting notable whale activity on-chain (source: @OnchainLens). Bitinfocharts address data for 125WeXgyrE4beiEeQewoaXf4H9BL5RiDoP shows the source wallet still holds 591 BTC valued around $73.67M as referenced by the report (source: bitinfocharts.com and @OnchainLens). According to @OnchainLens, the wallet initially received these BTC for $92K in total, implying an average acquisition cost near $133 per BTC based on that figure, underscoring a large unrealized gain that can influence behavior (source: @OnchainLens). Glassnode research on revived supply indicates that movement of long-dormant coins tends to attract market attention and can precede higher volatility, making these transfers tactically relevant for traders to monitor (source: Glassnode Academy, Revived Supply). Chainalysis analysis notes that sustained exchange inflows are commonly used as sell-pressure proxies, so tracking whether the two recipient wallets route funds to known exchange clusters may help gauge near-term supply overhang (source: Chainalysis research on exchange inflows/outflows). The cited post did not indicate an exchange deposit, so near-term monitoring of follow-on hops and address clustering remains the key on-chain signal to watch (source: @OnchainLens).
