On the one hand, the Funfury competition is a good idea to promote the casino and attract a new audience because it allows new users to get acquainted with the platform for free. On the other hand, if the Funfury competition leaderboard has thousands of users, that doesn't mean it's true. It should be kept in mind that any free promotion always attracts abusers, so there is a possibility that there might be a lot of bots instead of real users in this daily Funfury competition.
All free things attract abusers and cheaters but hopefully they have some systems in place to minimize that. Personally, I like this competition; already won 3 small prizes. The reward is not high but it is always nice to win some free USDT and BFG tokens.
