Unknown Whales Withdraw 1,090 BTC Worth $90M From Wintermute OTC Desk

Three Fresh Wallets, One OTC Desk

Three newly created wallets drew a combined 1,089.77 Bitcoin (BTC), worth about $90.4 million, out of market maker Wintermute in transfers tracked between October 20 and October 21, and on-chain analyst Lookonchain flagged the movement early on Wednesday. The Bitcoin (BTC) price stood near $82,750 at the time, up roughly 0.9% on the day, so the withdrawal landed with the market close to its strongest levels of the session. Each address was seeded first with a test deposit of 0.0002 to 0.0003 BTC, the kind of check a desk runs before committing a nine-figure sum. The first wallet then received its main payment in the same block as the second wallet, both landing at 21:30 UTC on October 20, while the third address collected its full balance just after midnight. Settlement figures read 364.09 Bitcoin (BTC), 363.64 BTC and 362.04 BTC across the three addresses, and the spacing between the funding events, all inside roughly three hours, points to a single coordinated delivery rather than three unrelated buyers. In Lookonchain's assessment the movement points to whales that keep accumulating, because coins leaving an over-the-counter counter for fresh, single-purpose wallets typically mark a completed purchase heading into cold storage rather than a trader staging a sale. Wintermute operates one of crypto's largest OTC counters, a venue where funds, companies and high-net-worth buyers take large blocks without disturbing exchange order books. The buyer's identity is not disclosed: no filing, fund announcement or exchange notice names the addresses, and the wallets carried no prior history. Whoever controls them paid only dust-level fees to confirm each destination, a discipline consistent with an institutional desk executing for a client rather than a retail holder splitting funds. That matters because OTC volume never shows up in exchange volume, so demand settled through desks of this size is easy to underestimate.

The withdrawal is the second large OTC exit routed through Wintermute within a week. On October 14, five other brand-new wallets collected 1,162 Bitcoin (BTC), about $96.77 million at then-prevailing prices, inside a 12-hour window, and combining the two episodes puts roughly 2,252 BTC, close to $187 million, through the same channel in seven days. That buying stands out in this month's broader Bitcoin market, where several large holders moved the other way. MARA, a publicly listed miner that maintains a strategic Bitcoin reserve, transferred 1,000 BTC to exchanges across five days, and a wallet that had sat dormant for ten years moved another 500 BTC, both flows that add sell-side pressure. Institutional flows lined up with the OTC buyers instead: US spot Bitcoin ETF products took in $527 million of net inflows on October 19, the largest single-day figure for the leading issuer in 2026. Listed treasury buyers compete for the same supply through capital markets, as Metaplanet's recently disclosed Bitcoin yield strategy illustrates. The market itself has been firm. A wave of short liquidations worth $45 million drove the price to $83,000 on October 20, the coin has closed above $80,000 for 33 consecutive trading days, and traders are watching $84,000 as the next level to clear. Distribution models put the ceiling higher, at $87,000–$87,800 resistance, with elevated volatility expected once that band is tested. The fuller level map lives in our Bitcoin technical analysis. One caution sits underneath: hours after the ETF inflows, Bitcoin quoted $115 lower on Coinbase than on Binance and OKX, a spread that usually reflects heavier selling from US spot traders.

Quiet Accumulation, Loud Liquidations

The tape and the counter are telling two stories about the same asset. Visible venues show US spot traders selling into strength, while the OTC channel settles blocks worth nine figures into wallets built to hold. Which side dominates depends on what the new owners do next: the addresses can sit as cold storage for years, back loans against the coins, or stage a fund launch, and nothing on-chain separates those paths yet. As of the most recent on-chain check, all 1,089.77 BTC still sat in the three addresses, unmoved since arrival. The owners' choice to HODL or redeploy has not surfaced in any public record, and until the coins move again, the size of the bet is the only confirmed fact.
