That's one of the most unprofessional thing i've ever heard from someone. And yes, who knows you may destroy your reputation for 400euros, cause the script you are using is free(can get on github), the domain you are using is free. Seems like you don't have any money to put in your bankroll(until you show some proof) and if this is the case, then yes, you'd destroy your reputation for 400euros.
Read above , you dont need to keep saying he need to show proof of funds or his bankroll because he wont and you are wasting your time here. As long as there is no investment feature then it is fine so far. No one will play here anyway when there is alot more better dice site, a site with coindice script is just stupid
