The amount will depend on the amount since you charge by percentage, in my opinion all swaps should be at 0.1%.

It is expensive to swap LN to Bitcoin (0.5%) and expensive to swap LN to L-BTC (0.25%).

If you lowered the fees it would be more popular and you would have more profit.

My humble opinion.
