Wagershare just stopped taking US players.
That will affect everyone’s stats. I am not sure any comparison at this time is going to be typical of their performance.
I suggest you allow them to regroup and retarget.
Any US players you send will not be able to play. Have you taken precautions to let your visitors know that?
If not, conversions will not reflect actual figures but your failure to send players to casinos where they can actually play.
