Why you should know this
Prices do not move because a chart decided to move. People, firms, protocols and infrastructure act for different reasons. Learning to separate who may be acting, what they may want, and what evidence we can actually observe helps us avoid turning a plausible story into a fact.
A whale is relative to the market

A whale is simply a participant whose position is large enough to matter relative to available liquidity. A wallet holding a large amount of Bitcoin may be important globally; a much smaller position can be a whale in a thin token.
The useful question is not “Is this wallet big?” but “Could this position materially change available liquidity if it trades?”
How a large order moves price
A large market order can consume several price levels in an order book. The average execution price then becomes worse than the first visible quote. A patient large trader may instead split orders, use OTC execution or hedge across venues to reduce impact.
Whale tracking has identity limits
A blockchain address is not the same thing as a known person. Exchanges, custodians and funds may control clusters of addresses. One entity can use many wallets, and one wallet can represent many customers.
A transfer to an exchange can be relevant, but it is not proof of an immediate sale.
Practice check — no money needed

Build a participant map with four columns: role, likely incentive, observable evidence, and one alternative explanation. No money or live trading is needed.
The goal is not to identify a hidden actor with certainty. If you can explain the mechanism, name the main limitation and state what evidence would strengthen or weaken your explanation, the lesson has done its job.
How this connects to market mastery
Participant analysis sits between market mechanics and market interpretation. The same habit later supports execution analysis, liquidity assessment, risk control and scenario building: identify the actor, identify the constraint, then test the story against evidence.
Shows why large transfers can have many motives and how to avoid trading on whale stories without evidence.
