SBD Total supply

Can somebody tell me the SBD Total or Maximum supply? I cant find it any where.

Or no limit?

When I put my money in it, it's circulating supply was 3 million. Now almost 7 million.

Some say it will be 1 dollar, as the blue paper (still) says, some people (i think who invested in it when it was low, like me), bring the attention to the rename of SBD, (STEEM BACKED DOLLAR-----> STEEM BLOCKCHAIN DOLLAR), in order to maybe this purpose of this coin no longer exist.

What do you think?
