How do liquidators get paid?

I'm curious to know, how exactly do liquidators receive compensation for their services? Do they get a percentage of the assets they manage to liquidate, or is there a flat fee structure? Are there any other factors that may influence the payment they receive, such as the complexity of the liquidation process or the time it takes to complete? Understanding how liquidators are remunerated is crucial in assessing the feasibility and potential profitability of a liquidation process, so I'd appreciate it if you could provide me with a detailed breakdown of the compensation structure for liquidators in the cryptocurrency and finance industry.
