How many new depositing players do you get each month? Because frankly, unless that number is astronomical (and proven), I don’t believe someone will pay 15k if you do not include the current revenue.
Noone here can know for sure if you didn’t recruit many players in the past, now the website has gone stale so you decided to sell. I’m not saying it’s the case, but noone here wants to shell out 15k and after the first month see 3 new players.
