Imagine you're lending out two different colored marbles to a friend's game. That's kind of like being a liquidity provider in the world of cryptocurrency. Here's the catch: if the value of one marble color goes way up while you have them lent out, you might miss out on some profit. That's impermanent loss. It's a temporary downside that can happen when you provide liquidity, but it's not a guaranteed loss. If the marble values even out, you can get your marbles (or cryptocurrency) back without losing anything in the long run.
