It's a consolidation transaction (a group of small balance addresses in the same #Bitcoin wallet being moved into a single address). 💁‍♂️

Each #BTC address included in a transaction has a data size, so consolidating makes the transfer "heavier" data-wise & will raise the fee due to the larger virtual size. In addition to that, they have also put the fee rate pretty high (at 5.05 sat/vB) for faster settlement. 🤷‍♂️

They should have set the fee rate to 1 sat/vB & just waited; it would have only cost them ⅕ of what they actually paid. 🤙
