I am wondering if anyone here has any recommendations for UTXO management best practices. Setting aside privacy issues (I am aware of those), and focusing only on future cost savings, how big should my UTXOs be? For example, if I have 10 bitcoins in cold storage, should I make one 10 bitcoin UTXO? Two 5 bitcoin UTXOs? Ten 1 bitcoin UTXOs? I am sure the answer is different for everyone base don their preferences and needs, but am wondering what people think. Thank you for your opinions.
