Have you read your own comments? "Technology perfected"is a key word. The technology has not been perfected is what SEC is saying. DECN has not perfected the technology if it is still being worked on and there's no validity data to substantiate their claim that it works. Those are misleading statements from DECN is the point.
If the CEO said that DECN is still trying to see if the tech can yield valid results then they wouldn't be suspended. Everyone bought this stock under the assumption that they are ready to receive approval whereas they don't even have data that proves this thing works or has been tested.
People are in the denial phase or stage of this. Reality will kick in on May 8th.
