Whale offloads $20.3m in wrapped Bitcoin
“A chain address sold 250 WBTC worth $20.3 million,” on-chain data aggregated by KuCoin’s flash news desk showed on May 15, without identifying the seller or their entry price.
Bitcoin was trading near $80,400 at the time of the transaction, down roughly 2% on the day. The broader market was already under pressure from surging Treasury yields and a fresh inflation print that pushed the 10-year note to 4.54%, its highest level since May 2025.
The wrapped Bitcoin sale compounds that pressure. WBTC operates as a 1:1 Bitcoin-backed ERC-20 token used across Ethereum DeFi protocols. Unlike native BTC movements through centralised exchanges, on-chain WBTC disposals bypass traditional order books and are harder to anticipate from exchange flow data alone.
The move fits a wider pattern of large-holder activity flagged across 2026. Crypto.news reported that CryptoQuant analysts rejected wider dump fears following a separate dormant whale movement in early May, noting no confirmed exchange inflows from that wallet.
Prior to that, a long-dormant OG Bitcoin address offloaded 1,000 BTC as selling pressure intensified, extending its total transfers to 3,500 BTC since November 2024. Separate data showed whales collectively adding 61,568 BTC even as price slipped, pointing to divergence between large-holder groups.
Whether the $20.3 million WBTC sale reflects coordinated distribution or isolated profit-taking remains unclear without further wallet history. Short-term price action continues to depend heavily on macro catalysts, particularly Federal Reserve policy expectations heading into the second half of 2026.
