Seems like whales are still sleeping this week.
Yes winter sleep. To get whales Bitdice must offer something interesting.
In the history when there were records broken in terms of wagering volume it was all one user playing same as it was on Betking
One user was playing martingale with 1 satoshi base have you seen that?
Whales do not really get that much excited on anything other than just competitions that give them a potential to have a positive house edge, aside from that you can't get whales to play. Looking at the competition the rewards are not really that high to justify a whale to gamble anything over 10 bitcoin, sure it is still something that drops the house edge because you get something but compared to other places that gives out tons of money for the competition it is really not that high here at all.
As long as you make a competition for wagering and give people 0.1 bitcoin or more (not the winner but the whole contest) than you may start to see it increase, I am not even sure if anyone gets anything from these leaderboards at all? I didn't see any prizes for being first but it could be something I missed out so I am sorry about that part. There was 28 people when I checked, you just have to do a lot more promotions to increase that, specially for a website this old, you deserve at least 100+
Their only marketing is here in Bitcointalk (sig+constantly bumped thread), they showed to us that they indeed know how to promote service if you were following their ICO they had active Steemit, Medium blogs, Twitter and ads on many premium crypto news sites including press releases. When ICO concluded they became quiet and silently spending tens thousands monthly on staff,server etc. blog is not regularly updated accounts on social media sites are inactive ( only thing is that Boxxob opened threads at various low traffic forums)
When they were on top there were almost zero competition and they never had huge player base (300+ users online peak when chat rains are enormous)
In reality when BitExo opened most of the players started playing there and few whales that remained played elsewhere and all that volume was made by few players that left the site.
They promised big things in the ICO while they just added some garbage third party slots and low quality sports book while competition offer much more games, competitions and almost all have active real live chat support, better interface, more active regular chat and high-end autobet features.
Look at some of their competitors Stake and Bitsler they are both unique and more interesting and keep customers engaged in their activities.
