So The problem is that they have reduced so much reward on holding steem powder even the price of steem is dropping reward should be high so it will attract new investors and encourage old ones too to power up more and buy more steem.

Get your facts straight, the changes in HF22 make holding SP more atractive since curation rewards are now 100% higher compared to pre-hardfork. Besides the drop in price happened way before HF21 was proposed. You are just sad that you can't use bidbots anymore.

I am glad that shitposters, bidbot users and operatos can't milk the system like before.
