Okay, so I have about 20 referrals now, but almost all of them just like playing several times and then produce 0 recent commissions a.k.a disappear. Is this because people who click on my referral are not the correct ones? Collecting free sats should be tempting to the one who currently doesn't have BTC, plus they can use it to buy lottery tickets to win big... I don't understand.

22 sats (assumed stable) x 5 (free roll) x 365 (days) = 40,150 sats minimum. With only playing five times per day for one year they can earn 40k sats guaranteed, with the opportunity to win more, plus earn compounding interest after 30k sats.
