I moved the BTC from my old wallet to BYDFi in one transaction

I cleared out an old freelance payment wallet this week. It had ten BTC outputs left, 0.01 BTC altogether before fees. I had a BYDFi deposit address ready, but I prepared a transfer to my own wallet first. I had treated consolidation as a compulsory bit of housekeeping before sending the money on. The review screen showed my own address, and I finally thought about the second transaction that was still left to make.

I made another draft straight to the deposit address with the same ten inputs. That already spent them together. Both drafts used the same ten inputs and one output, so I compared their estimated transaction sizes and fees at the same fee rate, deleted the transfer to myself and signed the direct one. The confirmed payment used all ten inputs, with the miner fee taken from the starting balance. I had emptied the wallet in one transaction.
