I have also the same experience with Betfury which is also beneficial to my funds since I could earn better in just a short span of time though Bitgame also has an edge though I think their dividend pool isn't that huge for their stakes. I believe that there will still be more improvements in the future.
Bitgame staking indeed has quite low rewards and if we compared it to other sites, it isn't really exciting for most users or might be the worst I guess. If I remember correctly, we need more than a hundred thousand of LUT to get a decent staking payout. I hope they could do something about this later, let's just wait and see for the good news from bitgame teams.
