With Bitcoin’s price climbing, network traffic - and fees - are set to soar.
Understanding coin control and making a plan when fees are low is key to saving on transaction costs and boosting privacy. Make every sat count by keeping your transactions lean and efficient. 🧵

Every Bitcoin transaction is built from inputs (UTXOs), and fees are based on the transaction’s size in bytes. Transacting with many small inputs increases the bytes—and the fees.
Consolidating smaller UTXOs (under 1 million sats) into larger ones during low-fee periods is a smart move to prepare for future transactions when fees may spike.

This example of a UTXO consolidation transaction chose at random in the Blockstream Explorer.
There are 27 inputs in the transaction, the input values range from approximately 0.0025 BTC to 0.1537 BTC, and the final UTXO size, or the total output, is 0.24794586 BTC.

Blockstream Green’s coin control feature makes this process simple. When fees are low, you can select and send smaller UTXOs to yourself as one larger UTXO, reducing future fees and keeping your holdings organized.
The result? Lower transaction costs if network demand and fees skyrocket.

Beyond cost savings, coin control also boosts privacy.
By labeling UTXOs, you can track which coins are linked to KYC exchanges and which are not, helping you avoid co-mingling them when spending—key for on-chain privacy.
