Very very useful and necessary information my friend! @eco-alex.
I would like to add something here. The wonderful tool https://steembottracker.com, created by @yabapmatt has an option tab 'currency' under which USD, Sbd, steem are listed. I think everyone should set the currency to sbd and also check the option 'Include 25% curation'. That will show the real vote value of the vote and the maximum potential earning after deducting 'curation reward received by the bot' because vote value shown in USD is always on higher side but the real value remains much low than that.
Also, 'total bids' do not show the actual position of bid received by the bot as it updated slowly. Till that time the bot may have received too much bid which results in a loss to the bidder. Most of the time someone sends a big bid to a bot when the bot has received the maximum profitable bid which results in a loss for every bidder, including to that person.
Your article is very useful in this situation. It is necessary to educate people on this matter which your post can do.
