SBD won't increase back up to it's USD soft peg unless there's a reason to speculate on it, or if it gets pumped and dumped again. People buy SBD with Steem to use minnowbooster and the like, but minnowbooster turns around and sells it again on the market for Steem, making SBD a contrived token. Its only speculative value is for arbitrage, and that use case is already controlled by whales that are betting on you trying to outsmart them.
