Yes, the Hive -> HBD conversion will likely have a strong influence on avoiding future HBD pumps.

But it's likely a script like this stabilizer will still be useful, because it is... automated. It doesn't get tired, it always pays attention and it works like clockwork every hour, checking the HBD peg and acting.

What we can't expect is the same level of profitability as the stabilizer + the HF changes improve HBD peg. Then it will probably be only marginal profit here and there. Same with Hive buy pressure from this bot. It will go down when HBD will be stabile.

But that's its main function to help with the peg, not to make profit or to create buy pressure for Hive.
