I think they should add ads to attract other investors.

You are the Hive marketing department. Your posts are the ads that attract new users. If you are a good creator and happy you are posting your work on Hive, you will be a better advertisement for Hive and draw more new users.

It seems you are unhappy you post on Hive because your rewards are being DV'd away. You will likely attract few new users because of that.

I wish more people understood these things.
