This is annoying and risky for bounty hunters at the same time before the three distribution phases come to past the token can lose its value and you will be left with few dollars, I'm not supporting this, it's better it team can only give up the exact amount of tokens they can release at once
But if it has been a decision and has been set since the beginning of the bounty, we cannot do much. If you don't agree with the system, then don't join.
IMO, it is a precautionary measure to deal with price reductions when investors and bounty hunters take massive selling at the same time, so it is anticipatory action taken by the dev team. We must appreciate this, at least if this decision is made from the beginning, then the bounty hunter can be more tolerant. However, in reality, many dev teams have made changes to these rules before distribution, especially when the project achieved good sales, of course, this makes the bounty hunter disappointed. It has been blamed because it is considered to be the cause of the dump, the reward is not shared in full, it is increasingly upsetting. Well, that's the risk.
