Large sets of small UTXOs can lead to higher fees when spending, as more UTXOs mean more data, and more data means a larger transaction size. Conversely, fewer and larger UTXOs can reduce fees and improve privacy by minimizing transaction linkability. Consolidation is the process of combining many small UTXOs into fewer larger ones.

Consolidating them into larger amounts when transaction fees are low simplifies transactions, reduces future fees, and takes up less of the limited space in each block.
