Change Output Detection: Tracking Real Transfer Amounts — full explainer
Why do the biggest crypto transfers look so confusing on-chain? Because most people miss the hidden pattern. When a whale moves Bitcoin, they don't send it in one neat packet—they split it. One output goes to the recipient, another goes back to themselves as change. That's where the real story lives. Change detection is how analysts separate noise from signal, spotting genuine whale movement buried in complex transactions. By tracking which outputs return to the sender, you see the actual amount moved, not a misleading total. This is how professionals catch major transfers before the market reacts.
