672 k powerdown in just a week, what is the main reason of such big amount powerdown in this low price market? Though there is a big ratio of staked value of steem compared to total supply, I see recently people is being interested in other social media over steem. But why steem authority is not doing something big tp attract more people and hold them here as before?

I still beleive in steem. Steem will obviously survive and be the king of all blockchain based social media. Steem is king.
