Now I still get a small profit from my referral, maybe about 10% of what I got last year.
Most of my referrals no longer play free rolls and also do not gamble
because maybe they used to be interested in deposit and gamble because of free rolls game.
That is probably mainly due to the increase in the value of Bitcoin over that time and natural wastage of referrals. I can speak on personal experience when I advertised my ref link years ago most of them played for a while and then gave up. All the ones that are still playing now have continued through the recent changes and I have exactly the same number of active referrals as I did a year ago.
I hope you and the team soon have a solution to be able to distinguish the botnet and the real user so that all policies can return like last year.
We are constantly working on that but part of it is the more attractive a site is in terms of how much free money can be made out of it the more work and effort botnet operators will put into exploiting it.
