What is SBD total?

Excuse me, could you please clarify what you mean by "SBD total"? Are you referring to the total supply of Steem Backed Dollars (SBD), a cryptocurrency token that is pegged to the value of the US dollar on the Steem blockchain? If so, the total supply of SBD can vary depending on the demand and supply dynamics in the market, as well as the specific rules and mechanisms implemented by the Steem blockchain. It's important to note that cryptocurrency markets are highly volatile and subject to significant price fluctuations, so the total supply of SBD can also be affected by these factors. Is there anything else you would like to know about SBD or the Steem blockchain?
