Blockchain transactions are public, yet much stays unknown. How ownership is inferred, whether exchange inflows mean selling, and care with whale alerts.
On a blockchain, when and how much moved from which address to which is fully public. That information is unavailable in banking, which is why a field grew around analysing it. What is public, though, is addresses and amounts; who an address belongs to is not recorded. There are traces without names.
Analysis services label addresses based on known exchange addresses and repeating patterns. Those labels are inferences rather than established facts, which is why services sometimes classify the same movement differently. Treating one wallet as one person is also imprecise, since people use several wallets and exchange wallets hold the assets of many users mixed together.
Assets entering an exchange are commonly read as preparation to sell and leaving as long-term storage. As a direction that has some logic, but individual cases frequently diverge. Moving collateral, swapping into another asset, and an exchange reorganising its own wallets all look the same on chain.
Overall trends carry more information than any single movement: whether the total held on exchanges has fallen over months, or how the share of long-dormant supply is changing. One large transfer is an event; a direction over months describes a state.
The same property applies to you. The moment one address is linked to you, its entire transaction history and balance are exposed. Posting an address you withdrew to in a public place creates that link. Where privacy matters, separating addresses by purpose is the better practice.
Knowing a few indicators that come up often in on-chain analysis makes articles and reports easier to read. Exchange reserves estimate the total coins held at known exchange addresses; active addresses count the addresses that took part in transactions over a period. The share of coins unmoved for a long time is used to gauge long-term holders' behaviour, and realised price averages the price at which each coin last moved. All of these depend on address labels and calculation methods, so values can differ between services even under the same name. Get into the habit of checking how an indicator is defined first.
Many services announce large transfers in real time. The big, instant numbers grab attention, but as covered earlier, in most cases you can't tell whose funds they are or what they're for. Exchanges shuffling between their own wallets, custodians reorganising storage, and the same funds counted multiple times as they pass through several hops make up a large share of big-transfer alerts. Reacting to alerts immediately means being dragged around by this noise. It's safer to treat an alert simply as 'this movement happened' and give it meaning only alongside trends over several weeks.
Anyone can view on-chain data directly on a block explorer. Enter a transaction hash or address and you'll see when, how much, from where to where, the fee, and confirmation status. It's also the first place to check when a transfer you sent hasn't arrived: you can tell whether it's still pending on the network or has already reached the destination address and the exchange is just slow to credit it. However, labels on explorer pages are guesses by the operator, and fake tokens or scam addresses can appear, so if an unfamiliar token shows up in your address, it's safer not to interact with it.
