What is Coin Control?

Coin Control is a feature in the BitBoxApp that gives you direct power over your Bitcoin transaction privacy. It allows you to manually choose which Unspent Transaction Outputs (UTXOs) are used when you send Bitcoin.

Why use Coin Control for better privacy?

By selecting specific UTXOs, you can prevent the linking of funds from different sources. This helps obscure your transaction history on the public blockchain.

Key benefits:

• Avoid linking addresses: Keep UTXOs from KYC (Know Your Customer) exchanges separate from those acquired privately.
• Strategic spending: Make conscious decisions about which parts of your Bitcoin to spend, based on their origins.
• Enhanced confidentiality: Gain a level of privacy management not typically offered by default wallet settings.

How Coin Control works with change addresses

Bitcoin wallets traditionally enhance privacy by sending any leftover "change" from a transaction to a brand new, unused address. This helps break the chain of ownership on the public ledger.

When you use Coin Control, you are manually selecting the inputs. The BitBoxApp will still generally direct any change to a new address for privacy. However, your careful selection of inputs significantly influences the transaction's overall privacy.
