Reading whales: what large wallet movements signal before the news

"A whale transferred X million to an exchange" is the most cited genre of on-chain analytics. Useful - if you read it correctly and not just the headlines.

Basic patterns

• Wallet → exchange: preparation for a sale (or for use as collateral/margin - not everything is a sale!). The weight of the signal depends on history: a wallet that hasn't moved for years weighs more than an active trader.
• Exchange → wallet: withdrawal into holding - structurally bullish behavior: coins leave the market.
• Accumulation in series: regular equal purchases to a single address - algorithmic position building by an institutional player.
• Internal reshuffles: most "giant transfers" from alerts are exchanges shuffling their own wallets. The main source of fake sensations.

Typical reading mistakes

Mistake one: one transfer = a signal. No: a signal is a series plus context. Second: "the whale knows." Whales are wrong regularly and publicly - their liquidations are a separate genre. Third: ignoring attribution - without a label for "whose wallet" (exchange? fund? market maker? government seizure?), a transfer means nothing.
