As for Dapps curating content there is a slight problem as it is not guaranteed that you will get upvoted. I don't really remember this but Busy curates either once every 12 hours or once every 22 hours and it also depends on the number of Followers you have. As for esteem there is no certainty of getting upvoted Everytime. Even if the posts gets upvoted it will still not be sufficient for the newbies. I have crunched in the numbers already.

Correlation of STEEM price to Authors, this is something I do agree on but what I wanted to say in my previous comment was that it is not that hard to bring in Authors but is surely hard to keep them Blogging on Steemit. I started 2 years ago and I hardly see the guys who started Blogging with me here on Steemit.

As for the Bid Bots I can assure you there are a lot of ways for them to be perfectly ok even after the 50/50 split. I can just give you one method right now. They can just increase the Minimum ROI from 10% to 50% and people would again jump in. You might say that it wouldn't be profitable for the Bidbot owners as they have to pay their delegators as well. There is even a way for that, they will be receiving extra Curation because of the 50/50 split so they can just power down some SP each week and pay the delegators. It's that easy. Even after doing that they can probably make a profit so I really don't see Bid Bits going out of Business. The Small ones might go but not the big ones.
