I have been trying to analyze, if steem users can actually earn money using bid bots here on the platform. The naswer is yes, but currently an avarage user is loosing more then it's earning using bid bots.
Example
Bot name: @booster
Voting round, which closed with votes ececuted at around 11.02/11.03 UTC on September 24, 2018.
Total Vote Value: approx. 37.00 USD (if STEEM price is around 0.87 USD/STEEM)
For exple, user @curatorbot has paid 30.000 STEEM (about 26.10 USD) and received approx. 15.00 USD vote on @zero-profit post. That is including curators reward, which means this vote can at the end have a net value of just 11.25 USD with maximum 25 % curation reward.
Total loss for bidder: between 43 - 57 per cent, depending on percantage of curation reward. Final analysis could be done after 7 days.
Conclusion: Users who voted in this @booster voting round made about 50 per cent loss on their bids
There we 2 main reasons for their loss:
users have relied too much or even ony) on Steem Bot Tracker (https://steembottracker.com/) tool.
If you look at the chart on top, you will see that this tool has shown no bits submitted in this round (Total Bids $0,00 of Maximum Suggested Bid 32.07 STEEM). I don't know what was the reason for that. This happens actually very often.
There is currently simply not enough bot power for all the demand from users, who place their bids. Gross margins, which users can receive are very low, but when you deduct curation rewards, most of the users are in red figures. They just don't realize that.
