The way things have been its pretty much important to use in any worthy post to get any decent visibility. I use minnowbooster and randowhale the most and then go to the bidding bots using steem bot tracker and use them if still profitable as no point if the return is less then you put in.
Yes the problem is other people are not looking at that tool and throwing bids blindly.
This resulting in the bids at a lose. That person not only ruin his/her return but everybody who bid on that bot first.
I have asked bot creators to put a command line to stop the bid when ratio is 1:1 so no more bid as it will just be unprofitable for the bidders or worst end in a lose.
They replied to me saying they have tried that before and people complaining that they can't put their bid on.
