looks like a student's project rather than  a legit gambling website,to be honest with you
a piece of advice-do not attempt to create anything that you do not have money to run
a gambling site requires a certain bank to be able to sustain losses,do you have any proof of funds?that you can pay me if I win?
there is no login system,come on it is 2018-any problem with my browser's cache or cookies and I lose all my money
not going to check the provably fair there since the things I posted above should be enough to get discouraged from depositing real money
