In what I have Understand, SBD was not meant really for enforcing $1 only but sbd is created to make steemit profitable not go lower than $1. That is the use case of sbd to prevent inflation.

Market manipulation may presented all the time but it cannot be denied also that it is the traders who contributed much how a coin value goes,

all crypto including steem/sbd is subject for volatility as it was paired heavily to btc and not to usd.

• the basic law for trading is buy low and sell high, and buy low again and sell higher,

If you don't like Steem trading to SBD, you can either trade in exchanger, like SBD to BTC or Steem to BTC, Same rule applied; Buy low sell high, or sell high and buy low
