Witnesses have already implied they are ready to peg the other side of the SBD-->Steem conversions, thus this creates a near/medium term catalyst for SBD to go down; HOWEVER, anytime something is so easily logical, and the price does the opposite, you should look for a DIFFERENT catalyst. Is someone in Korea or elsewhere trying to corner the market on SBD right when Steemians are seemingly selling every share? Is there just a wierd craze or promoter there getting people to buy? Maybe forex buyers think SBD is the real Steem? Maybe they are selling out of their crypto, and people doing so think SBD is pegged to the $USD so it's a backdoor out of crypto and into fiat?
You can bet there's an explantion for why SBD can outperform Steem, we just haven't seen a convincing one yet. Until someone comes up with an explanation, it's our experience the odd price movement will continue.
Rec? Don't sell ALL your Steem, let it out in small doses until something comes out of the woodwork.
