When you provide liquidity to a liquidity pool, you add 2 different tokens and you get LP Token (liquidity pool tokens).
You can recover your 2 tokens amount when you give back your LP Tokens, decreasing the amount of liquidity of the pool. The only way to ensure the liquidity is to lock your LP Tokens during some time, with. Unicrypt, Mudra locker or similar.
Impermanent loss can happen if the pair price changes, because there will be more tokens in one side and less tokens in the other side of the pool.
Now: Imagine you put fooTokens and ETH in a liquidity pool, but you lock your LP Tokens. Could you loose most of your ETH (liquidity of one side) if there are big sales of fooTokens against ETH (fooToken/ETH price decreases), even if your LP Tokens are locked?
I think so, but a lead developer tells me that most of their ETH are protected because they have locked their LP Tokens with Mudra Locker. I think that if someone sells a big amount of fooTokens, he could get most of the ETH tokens provided as liquidity. Any idea to confirm?
