To me, I think it's a contest for whales, aside referrals, the more money you have and wager, the higher your chances of winning, it's not a contest for plebs like me.
Plebs have to find a way if they want to take part in a contest like that, one of which is by getting lots of referrals, it's not easy to be able to do that, but if we are in a community that likes gambling and they don't know about freebitcoin, we can invite them to play here, especially since freebitcoin has long been a casino a trusted one and you don't need to explain about KYC to your friend because freebitcoin will never ask for it.
Honestly, I think there is no reason for a regular user to participate neither in the wagering contest nor in the referral contest because some whale has already gambled more than 44 BTC, while the other user probably has this whale as a referral, and as a result, he is in the top 1 in the referral contest. Furthermore, let me remind you that Freebitcoin already has more than 50 million users, and it seems to me that now it's hard to find users who are fond of crypto gambling and still haven't heard about this site.
