Unspent transaction output (UTXO) count of bitcoin (BTC) is ticking upwards, set to challenge its all-time high of 84.6 million from November 2022, when there was a flurry of on-chain activity as traders tried to escape the wreckage of FTX’s collapse. UTXO refers to the individual units of bitcoin, called satoshis, or sats, that are locked in transactions on the blockchain.
