no real demand I am afraid. These are market makers or even owners of that site who put these "orders" there. They "pretend" (invent) demand there placing big qty of bids ad asks, often with ridiculous prices, and trade between themselves. I noticed this when put a buy order, Immediately they started to outbid it and place many fake orders, thought there was no trading at that time at all.
This is kind of the breaking point of crypto and the only way to stop it is to have much demand and history of that coin based on some value. It could be the real price, it could be fake. Ppl demand WTT now?
