some bots, like me have now started adopting a minimum roi rule.

Mine is set for -10% so you will never get less than -10% roi using sneaky ninja.

If you are worried about overbidding then when using the bot tracker look for bots with an roi setting. if there is no setting then that bot can be overbid.

Bots were basically designed for getting posts noticed, not really for profit.

To obtain positive roi you have to look at it in long term.

For instance if you put $5 sbd into a post and get back $4 you can then use that same $4 again on another post. You can keep doing this until all of that has been converted into your sp. Thinking long term like this always produces a hefty roi on your original $5.
