I also thought it was a statistic of the number of users who registered Betkin accounts, not active customers who played. One of them might be the impact of their signature campaign launch. I'm sure it's quite a lot of users if you see there are quite a lot of participants who register.
I created an account here some time ago, but I always see users who are online at different times, which is not enough. From the statistics shared, there may not be half. At least, that's what I see.
A signature campaign and a condition to have an account for application submission, is reasons for people to register on Betkin.com. It's nothing bad, and it's part of marekting from any company, because marketing such as signature campaign is to expose the company brand to more people, get as most new users as possible.
By requiring applicants to register accounts, the company can turn some of them to loyal users on Betkin after a long time.

Even if you don't have an account there, you can still see what kind of bets are being made and how many people are staying at the Betkin casino. You can see this if you visit the Betkin site.
It is about online users and don't give extra details about Nationality of users, nothing to support a stats table, and sure it is not my concern.
