Yes, it may be so. Some of projects end dev go with money
You are not thinking,the domain is up until 2020 and 1000 Bitcoin is to little to run at this point of time,they have build their business for over a year and they had a good number of members,they can still make a lot of money and run this business for a long time and they know that,because they are putting a lot of advertisement.
why would they run this business? they'd be out of money once this is on the exchange because all these investors are going to dump everything and they be left with nothing and they don't want that. they'd rather scam than list the coin on exchange. people scam for 200 btc if its true they've gotten more than 1000 btc, you may never see them here again.
