Do you have a bounty program? Usually they run a bounty program on the forum. I think for you it should be very interesting!
we don't have a bounty program, but we can make one in the near future, you think it might be efficient?
Bounty/campaign + good offers (regular) on your site will be effective and efficient. Bounty alone is not enough to attract players, as most people has their own favorite site already. The most important thing to think is about how you make players come and stay on your site as long as possible. Bounty/campaign may attract players to take a look on your site only, but it does not guarantee they will stay. So it is better to combine campaign and offers such as regular tournament, promotions, giveaways, etc.
This is exactly what we are thinking now. We are agree that, as you said, regular tournament, promotions, giveaways, these things will make users stay and play.
However, we realized that a lot of BTC dice games have the same things. So question is how to stand out among other BTC games? We have one of these solutions is to use - Stake mining via EOS Blockchain, however, as reward you get daily BTC payout. It will be available next Monday 8 April.
Just imagine, lot of btc gambling games have no such features, where users can get some amount of BTC without risks. We are adding it.
