Approximately half a day ago, large buy orders were placed on the stock exchange. At the current trading volumes this "buy-wall" will stay for a very long time. This puts pressure on the price. And we will go lower and lower, i think.
Why do devs want to buy such huge amount of SBD? They want to reduce the amount of SBD in circulation? They want everyone to be able to buy cheap STEEM? It's unknown.
