blackjack.fun will get more attention because games and rounds one of the most active threads.
This statement can be correct and also false.
Because the attention is also depends on the type campaign it self & how the rules of the campaign. As you know, we can take example a contest promotion like Duelbits some of the scenario only have under 10 entry.
Free stuff is always get the attention comparing need some money to join the campaign.
Yes I know about it, attention I mean they don't have to participate in the contest just imprinting in their memory that there is a site called blackjack.fun as well as a great way to build a reputation. Regarding DB , sometimes there are players who are not able to compete so they decide to only be active players especially whale players they don't like this kind of contest because their base bet is equal to the total prize.
