I'm not the owner but your timing may be late since if you check its "24h volume", there were XMR reserves.
It's just this coin is very in-demand.
Poloniex had XMR withdrawals closed for about a year and still had high trading volume. Trading volume is just a fiction with most exchanges. But it does not interest me as a customer. I need real coins. However, their treasury is still empty.
High demand? I don't think so. Why do you think that? Apparently they have some other problem.
