Just after a week of HF20, rewards for my posts increased. Now, I am seeing that the overall rewards are decreasing on my posts. I think the low price of steem is the main reason. Some days ago my voting value at 100% voting power was just 0.025. It is still around 0.26 even after I powered up with 50 Steem. I don't know what is really going behind the steem reward distribution system as I was not very active in last week.
