The team is still active but they don't care about the price. I have seen some people asked the developer about this several time and they are always giving the same answer said they are still focus on the product.
It looks like the orders were getting drowned by someone or those people who have been putting orders cancelled it?
This is what I called the lack of understanding or a different views on dev vision and goal for the coin, leading to a lot investors feel coin inaction. So investors slowly lose their patient and interest. They sold their bag and move on differrent coin, I think.
