Power up & rewards Tax, I'm not in for that.

Power down tax seems good, but 10% is also a huge amount as compared to defi or other protocols, but yes, to get gains over pump, 10% wouldn't matter. So we can have discussion on this. Also there should be options to lower the power down period with penalty, so people can decide which option is best for them.

People who power up hive, are mostly not traders to catch market. It makes sense to have some decent portion of liquid hive if someone wants to take the advantage of price action. Powering up gives much more benefits for stakers as you already mentioned above.
