YoY change in STH cost basis — Year-over-year change in short-term holder realized price (cost-basis momentum)
STH realized price YoY uses Bitcoin's UTXO cost-basis data: YoY change in STH cost basis. It connects the current market with the prices at which coins were last moved.
Look for changes in profit, loss and holder cost basis across weeks or months. Those shifts show whether the market is absorbing supply or realizing stress.
Cost-basis metrics describe on-chain movements, not every off-chain trade. They are best read as a market-structure view, not a guaranteed buy or sell signal.
