But after the birth of bidbot almost all good content has no price at all, one way to encourage themselves is to use bidbot.
That is not true, well it was before the last hardfork. After that, bidbots are moreless irrelevant, or more, community is trying to get rid of those. That is why so many Curangels and Curies and other programs to upvote valuable content came accross.
Whales has more SP, so they can "upvote sh.t" and it will have more value in STEEM/SBD than quality content. But that is true and was true. But still, downvoting commandas are fighting at least against the misusing the upvotes of ones own comments (did by whales).
My advice - don't use bidbots and you will profit from it in the long run. Write quality content, put quality pics in it and the "curators" with big SP will find you.
I'm not saying that using a bidbot is right, it's totally wrong, but you can understand my previous comments. Now we have to know how to remove the bidbot (maybe one of the ways is with the big whales here), because we know, the bidbot is also a big whale but they use their evil intentions for personal gain.
For quality content it's clear as you say, because one of the goals of Steemit is indeed for that. I support the performance of good people here.
