I explained above why SP is needed. You can refer to it.

We need to build various MM bots and systems. During the development period, we will need the support of DAO.

I did not submit SPS because it is currently under discussion.
If everything is discussed, we will submit SPS and start voting.

This MM bot is not intended to artificially keep SBD at a high price.
MM bots and strategies are very diverse. We only provide liquidity through MM and react to market price changes.
And it is difficult to create market price changes with 10K USD of liquidity supply.

How much STEEM can be burned will depend on the trading volume and market conditions.
