I fully agree and have another poker room which matches all the criteria mentioned above, this is: https://blockchain.poker/
It is very easy to set up a private tournament there, is fully anonymous and supports cryptocurrencies.
I have played there already multiple times and never had any problems with withdrawals or the gameplay itself.
Literally, in a few clicks, I was able to set up a private tournament there.

There is a fee of 10$ for a private tournament on this website, but really even a child would be able to set up one there.
Here the summary page with created by me tournament, of course, one can adjust any settings, how many chips, minutes, people, etc.
If this will be possible to set up this tournament somewhere else (not on Sportsbet), where I will be eligible to play, then you can count me in too, of course.
