@ranochigo, I am still learning and getting to know more about bitcoin. I was just confused about what LoyceV posted, and I want to know more about it. I will be so thankful if anyone can recommend me a book I can read to fully understand this.
https://github.com/bitcoinbook/bitcoinbook/Consolidating inputs means that you're taking many UTXOs (eg. 10 x 0.01BTC) to spend and convert to a single UTXO in the output (1 X 0.1BTC). Taking into account what I said, spending one UTXO can save you a lot of space as the transaction would only have 1 set of signature and public key as opposed to having spend 10 sets of signatures.
When you consolidate them at a low fee, you don't have to spend a lot more when the fees are higher.
