Hi there,
Try to make me understand this one crucial bit of information which I can't really get my head around. You say that 70% of the profit goes back to your players, then how do you maintain a long-term business, how do you generate profit FOR YOURSELF? Say of the remaining 30% you pay what up to 20% to run the business properly, and if you look at your finance risk you'd soon and quickly learn that what you have is a business which spends more than it actually generates - bizarre, right?
Unless, you're going to correct yourself on that 70%, how do you justify such a large loss, and most importantly how do you think you'll survive for the long run?
not 100% sure but this would mean that they offer an investment programme for gamblers
you can invest into the site's bankroll and be the house
this way the casino shares up to 70% of its revenue , keeping 30% to continue the site's development , pay for affiliate , buy marketing promotion etc.
public bankroll ensures that the money invested are working for both investors who get to share the house advantage over players due to the house edge and profit in the long term
and for the owners alike , who get an increased bankroll that attracts whales and proves that the casino has a solid financial standing
and is going to pay even the highest wins without going bankrupt
the tricky part is to provide a secure and transparent investment system and to attract enough investors so it is worthwhile
but goodluck to us for completing those challenges
