Sorry for the late reply, I've been busy with other things like work, gardening and enjoying the little bit of sunshine that we get here in England!

Some bidbots are more profitable than others. With some, like @tipu and @bdvoter you are guaranteed a profitable round. Others like @boomerang are risky, (possible negative round) but you can also get very profitable rounds. But with many of them, you will just get your money back if you are lucky!
I haven't given up on Steemit, just not posted for a bit.
I hope you are well. ✌️
