@0x31ecc69e40be85b3017fdbad9bbbd657cfb30dfc Yes it is 'impermanent' in that it only becomes a loss when you withdraw your liquidity. It is caused when there is a large change in the value of one or both of your tokens in relation to each other. If you don't withdraw your liquidity when you have impermanent loss and the value of the tokens returns to their original values then you won't suffer any loss.

@CryptoGeezer the loss is buying MM ... stop crying @CryptoGeezer
