Unit 1 · Level 2 · Whale watching
Exchange inflows & outflows
Coins sitting in a private wallet can't be sold on an exchange. They have to be deposited first. So when whales send large amounts TO exchanges, analysts read it as possible selling pressure; large withdrawals FROM exchanges read as coins going into storage. It's one of the oldest signals in on-chain analysis, and it's wrong surprisingly often. Knowing when is the real skill.

What you get asked
Why do analysts treat big exchange INFLOWS as a bearish hint?
You can't sell from cold storage; selling requires moving coins somewhere with a market. The inflow doesn't cause the drop; it hints at the intent.
A whale deposits €20M of BTC to an exchange. Which INNOCENT explanation should you rule out before yelling 'dump'?
Exchanges reorganise their own wallets, market makers rebalance inventory, and traders post collateral for derivatives. Plenty of big inflows never touch the sell button.
Match each flow to its textbook reading (they're hints, not verdicts)
Note the asymmetry: coins in mean possible selling, but stablecoins in mean possible buying. The direction of the hint depends on WHAT is flowing.
The deposit-to-sell heuristic fails when a transfer is really an internal exchange ___ rather than a customer preparing to sell.
Exchanges constantly shift funds between their own hot and cold wallets. Without good labels, their housekeeping looks exactly like a whale deposit.
What's the honest way to use exchange-flow data?
Flows are a real signal with real failure modes. Treat every big flow as a question (who, why, what else is happening?), never as an answer on its own. 🐜
