I somewhere saw the idea: Reverse convert and convert for SBD and STEEM to peg SBD to 1 USD.

For example, if SBD is less than 1USD, it can be converted to 1USD equivalent of STEEM, conversely, if SBD is above 1 USD, then STEEM can be converted to USD equivalent of SBD.

For example, if STEEM is $4, then when SBD is below $1, it can be converted to 0.25 STEEM while SBD is above $1, STEEM can be converted 4 SBD.

I don't know how the supply of both SBD and STEEM come form. If somebody can explain the supply source of both "SBD and STEEM" in this convert scenario, it will be helpful.

However, it will definitely peg SBD to 1 USD. There is a market demand for 1 USD pegged such as Tether or NuBit, most importantly, it will be helpful in future internal exchange for SMTs.
