Glad you asked, the Burning Bid-Bot can offer you things that Minnowbooster can't:

• The Burning Bid-Bot offers you 100% of earnings while Minnowbooster only offers you up to 85-90% profits due to the fact they have a flat fee, we don't.
• Delegating to the @lrd Burning Bid-Bot you have a chance to receive the random lottery payout giving you additional Steem (there is no such feature in Minnowbooster).
• If you are the largest delegator you'll receive 15% of curation rewards (there is no such feature in Minnowbooster).
• You are helping reduce the Steem supply due to the fact that 5% of curation rewards are burnt.
• We have a promising Roadmap (read above) in which we will keep on improving the Burning Bid-Bot an adding to it more features.

If you have any other questions we will be happy to answer.
