Whale
A holder or wallet with large enough holdings to materially move market prices through their trades.
In Bitcoin, the threshold is roughly 1,000 BTC — enough that a sell can dent the order book on most exchanges. In Ethereum, ~10,000 ETH. In smaller-cap tokens, even 0.5% of circulating supply can qualify since order books are thin.
Whale activity is closely watched because their trades often precede broader moves. Glassnode and Whale Alert track large transfers between wallets, exchange deposits (potential sell signal), and exchange withdrawals (potential accumulation). Sustained whale accumulation through bear markets has historically preceded recovery cycles.
Not all whales behave the same. Long-term holders move rarely. Active traders/funds move daily. Exchanges hold massive cold-wallet balances that make them appear as whales on-chain but are actually customer balances. Distinguishing user-whales from infrastructure addresses requires labeling work.
Whale flows are a leading indicator of price moves. Tracking exchange deposits/withdrawals from labeled whale wallets reveals where smart money is positioning.

FAQ
How big is a Bitcoin whale?
The convention is ≥1,000 BTC. There are roughly 1,800 such addresses globally. Below that, "shark" (100-1,000) and "dolphin" (10-100) tiers are sometimes used.
Are exchanges considered whales?
Their wallets hold whale-sized balances, but those represent millions of customer accounts, not a single decision-maker. Most analysts exclude labeled exchange wallets from "whale" counts.
Can whale activity predict price?
Imperfectly. Large exchange deposits often precede selling, large withdrawals often signal accumulation, but whales are wrong as often as anyone else — and sometimes deliberately bait the crowd.
Where can I track whale movements?
Whale Alert (Twitter), Glassnode (paid), Arkham Intelligence (free), Etherscan/Mempool.space for on-chain inspection.
