I'm very serious about my site and as I once told players will realize this in time.
yet you dont care that your site is not provably fair. interesting.
If u look at it like this no site is fair, coz lets talk for pd , u wait 24h to see secret. So u saying he can try 100 combinations and come up with one suited for him in couple of m sec, and u have all u need to check it instantly , on pd u need to wait 24h in that 24h same can be done but it isnt, not sure how it is on JD thou.
They will make more profit if they dont cheat. Only thing why bet is delayed is coz of server lag, its hard to make it so bet is done in that msec when u click on the button.
pd uses the same key for the day, they cant manipulate single bets.
pd has been around for a while, pd is reputable. this is some new site with an unknown owner with a negative trust. are you really that naive?
as for the 100 combinations in a couple of m sec - not a problem. it is only a question of calculating a hash. if your hash rate is 10million hashes per second, do you really thing bruteforcing 100 combinations is a problem?
