Minimum self-bond amount: Minimum amount of FX the validator candidate need to have bonded at all time. If the validator's self-bonded stake falls below this limit, their entire staking pool (i.e. all its delegators) will unbond. This parameter exists as a safeguard for delegators. Indeed, when a validator misbehaves, part of their total stake gets slashed. This included the validator's self-delegateds stake as well as their delegators' stake. Thus, a validator with a high amount of self-delegated FX has more skin-in-the-game than a validator with a low amount. The minimum self-bonded parameter guarantees delegators that a validator will never fall below a certain amount of self-bonded stake, thereby ensuring a minimum level of skin-in-the-game. This parameter can only be increased by the validator operator.
