Should We Fear Investors Leaving Because Delegating To Bid Bots Is No Longer As Profitable As Before?

The answer is we don't know because we don't know how savvy delegators to bid bots are at utilizing other ways to earn passively. All I can say is that there is at least one such way to earn passively. The obvious choice under the 50/50 author/curation reward split is to set auto-votes on content created by authors who are likely to earn high author rewards. The trick is to front run most of the voting power spent to upvote each post. Earning 70-90% of one's vote value is really easy unless your stake is so massive that without using small fractions of your voting power at a time, you'll have difficulty finding sufficiently large chunks of voting power to front run. In that case, you may need to do some digging to find authors who post consistently and who already get some support to do your voting in smaller pieces at a time.

The best part of this is that you don't even have to vote abusively to earn nicely by curating. What I recommend that you protect the long term value of your investment by steering clear of bid botted crap or voting circles posting trivial content to milk author rewards. Instead, go through trails by reputable curation projects and find authors worthy of rewards and set your auto-votes. If your stake is really large, you'll just need to find a number of authors who already receive regular support larger than most people do and front run that regular support. Then you can go fishing or whatever it is you like to do instead. There is no need to power down and dump your stake at this kind of low price. That would be like selling BTC at $100.

Another way that does much less harm to PoB than delegating to content-agnostic bid bots is to delegate to @ocdb that distributes 10% of its rewards to whitelisted authors under constant quality control and 90% to its delegators.
