Curve Impermanent Loss
The first graph is going to show you amount of money that was lost to impermanent loss each week. Impermanent loss is the risk that liquidity providers take in exchange for fees that they get from the different liquidity pools. If the impermanent loss exceeds fees earned by a user when they withdraw, it means the user suffered negative returns compared to if they just held their tokens outside the pool. As you can see the fees earned are drastically higher than the loss per week meaning for most users it was a great idea to take the risk.
