Try Quests to earn cryptoBonded vs Unbonded
The LUNA market seems volatile. When a Luna is Bonded, it is staked, meaning it will generate rewards for the validator and the delegator it is bonded to. Until it is fully unbonded, it cannot be traded. The graph shows that Luna has been going up and down. It stays at those high or low points for around 2 months before either going back down or going up. You could argue in that case that it is stable, however, because of how drastic the changes tend to be, I would argue that LUNA is not consistent, but it is stable.
