Yes.

Most of the well known bots are reliable on Steemit.

In terms of risk/reward, fixed rate offer virtually no risk, with low reward. (I personally prefer and recommend fixed rate)

Bid bots offer a higher risk, with a higher potential for reward. (in some applications) Many bid bots offer a max ROI of 10 percent, but the potential to lose 10 percent or more.

For Bid bots. Check out: https://steembottracker.com/

For fixed rate, I recommend:

Minnowbooster

Smartmarket

tipu

I hope this helps.
