It was the case that a stablecoin was listed on binance and it pumped from $1 to like $1.30, it's all thanks to bots in my opinion. Then there's the rampant use of bidbots, that's sure to drive up SBD.

Recently though, I've noticed SBD and steem are no longer the same price. There was a point when sbd was more expensive, but I think projects such as @burnpost and a general change in attitude toward bots are helping to drive sbd down and drive steem up.
