Bitcoin (BTC) whale wallets added a net 88,987 BTC over the past month, pushing the cohort's combined on-chain balance to its highest level in six months — a level last reached around April 2026 — according to data published by COINOTAG.

The accumulation figure stands in direct contrast to listed Bitcoin funds, which shed assets over the same period. COINOTAG highlighted the divergence in an update issued at 17:14 UTC on October 20, 2026, noting that on-chain whale balances are rising while listed funds record outflows.

Whale wallet activity is a standard metric in blockchain analytics. The term "whale" is commonly used for wallet addresses holding 1,000 BTC or more, and because Bitcoin's ledger is public, the aggregate balances of large wallets can be tracked directly on-chain. Bitcoin's capped supply of 21 million coins makes the movement of coins between wallet cohorts a routinely monitored indicator on analytics platforms; against that fixed cap, the month's net addition of 88,987 BTC represents just over 0.4% of all Bitcoin that will ever exist. As with all address-based measures, whale balances track wallet addresses rather than identified owners, since a single entity can distribute holdings across multiple addresses.

On the fund side, spot Bitcoin exchange-traded funds listed in the United States began trading in January 2024 and disclose their holdings, making the split between on-chain whale accumulation and fund-level outflows visible in publicly available data — and leaving any further divergence between the two sides open to monitoring in the same sources.
