check my post about steembots and be aware that if you are bidding even for a big whale bot you could lose money, never go with the highest bid, rather try to use an average of what the rest did. If you go with the highest profitable bid, chances are someone will come to bid right after or at the same time, making the bid non profitable for you and all the rest.
Long story short if you have a bot that the vote value is 300 USD and you bid 100 USD and there are 150 people more bidding 1 USD you are not making enough to payout your 100 USD bid, you are only giving away money for a whale which will be happy to take your money.
