Lol classic misstep ;) . Been there.. Not that you asked, but, I will give you my "tip" for using bots. It has yet to steer me wrong. What you wanna do, is:
First, wait until a bot has around 3 minutes left until until it votes (last column on the right). This allows you to be sure that everything is in order, and hasn't gone haywire before giving it your money.
Second, take a look at the column entitled "Max Suggested Bid." This basically tells you how much sbd is left, over what users have bid, and under what the bot's vote is worth. In other words, if there is a positive sum here when the bot votes (this part is key) then the bot will be profitable. .
I also like to choose bots with "none" as its "max ROI." Some bots will cap you at a 10% return--why limit yourself??
So yeah, the higher the figure in the "max suggested bid" when the bot votes will determine how good of a return you will receive. This also requires you to pay attention to the minimum required bid bc, you don't want to be paying a "minimum" bid that's, say, 1 sbd, when the "max suggest" (remaining "profit") is only, say, 0.50 cents, right?! Right.
So.. yeah. Give that a try, if you like; lemme know how it turns out...
