Do you have an event like a demo account? What if we wanted to do a trial first?
I made a deposit before trying a few similar platforms, but then I had problems due to some doubts. After that, I decided not to use it without trial.
There's no demo account but there's a faucet in their feature just check it out.
I suggest to them to have a giveaway at least 10k satoshi exclusive for bitcointalk to try out their gambling site.
