What is Whale?
A holder large enough to move a market on their own. Whale wallets are watched obsessively because their sales can become everyone else's price action.
A whale is a holder big enough to move the market — early adopters, funds, exchanges' own wallets, and in Bitcoin's case a few famously dormant addresses from the earliest era. In thin markets a single whale's sale is the price action; even in Bitcoin, large wallet movements get watched obsessively as possible intent.
The watching has limits worth knowing: a transfer to an exchange isn't a sale (it might be custody reshuffling), clusters of addresses may or may not be one owner, and "whale alert" accounts generate more anxiety than information. The tradeable insight is structural, not tactical: coins with concentrated ownership carry a standing risk that someone else's decision becomes your drawdown — supply concentration is part of what separates the calm coins from the wild ones, and blockchains make it publicly checkable.

FAQ
Should I follow whale wallets and copy their moves?
The record is poor: transfers are ambiguous, whales hedge elsewhere, and by the time an on-chain move is public the market has often repriced. Whale-watching is better entertainment than strategy.
How concentrated is Bitcoin ownership, really?
Less than raw address statistics suggest — the largest addresses are mostly exchange cold wallets holding millions of customers' coins. Genuine concentration analysis has to net those out, which serious studies do and headlines don't.
