Sorry, but I don't think the value is that high. Reasons:
1. Poker domains do not sell like before.
2. Onlinepokertoday.net, .eu and .co.uk are available to register.
3. There are so many choices out there.
4. I have Onlinepoker.xyz. No interest in that one for 3 years.
But best of luck! And Onlinepokertoday.com is taken so you never know.
