UTXO Management Workshop
summary
Shows step‑by‑step UTXO consolidation using Cold Card Q with a QR air‑gap (BBQRS) into a watch‑only wallet on nunchuk.io, creating a PSBT, signing offline and broadcasting. Demonstrates consolidating five ~50,000‑sat UTXOs, compares one‑output vs ten‑output fees (≈10,000 sats vs ≈72,000 sats, ~1% vs ~7%), sends at 2 sat/vB then uses RBF to bump to 5 sat/vB and achieve confirmation in about four minutes.
