Bitcoin whale tracking monitors the largest BTC holders — typically exchange cold wallets and early Bitcoin addresses holding thousands of BTC. When whales move large amounts of Bitcoin, it often signals upcoming market volatility.
We monitor verified cold wallets from major exchanges: Binance, Coinbase, Kraken, Bitfinex, OKX, and Bybit. We also track the famous Satoshi-era wallet (1FeexV6b...) which has never moved its coins since 2009. All data sourced from mempool.space in real-time.
Wallet balances refresh every 5 minutes. Mempool fee data and mining pool statistics update in real-time from mempool.space. Our free API provides the same data programmatically for trading bots and custom dashboards.
