Frequently asked questions
Why is it called impermanent?
If prices return to where they were when you deposited, the loss disappears. It becomes permanent when you withdraw at different prices.
How big can it get?
A 2× price move costs about 5.7% versus holding; 5× costs about 25.5%.
Can fees make up for it?
Often — pool trading fees can exceed impermanent loss, especially in high-volume pools. Compare your fee earnings with this number.
