It seems that bitcoin poker is not profitable anymore, too many sites close their poker game in the last few years. But it is a good opportunity to the existing site such as swcpoker and nitrogen. Betcoin poker player may move to one of the existing site. Regarding the 40btc badbeat jackpot, lets wait for the official announcement.
Unless there is a lack of advertising, I am not sure how the site could not be profitable. I understand security and site upkeep, but I am sure they take in enough on the rakes for these games to make a nice penny.
