1st Query
Why don't you hire some big hackers for checking any bugs or exploits(which could ruin your reputation seriously)? Now this is a serious query because hacking is a thing which always has risk for everyone and all know how prevalent it is
2nd Query
Why don't you add the feature of sending confirmation link to email when someone requests a cashout(and if big then for certain) and only process the request when the user clicks that email link?
If you add these two things then it will boost your credibilty and trustworthiness thousand fold and help you in your business promotion and also be convenient for us(the second query of course surely convenient)
Both of these things are already taken care of.
-> ADZbuzz is being completely rebuilt in Laravel PHP framework by 9 developers making it completely bug-free and perfect for scaling with faster load time.
-> 2FA will be added soon as the launch is done, which is something we are working on together with a more accessilble version (without API) of our payment processor.
So yeah we got that covered but it obviously takes time to develop. We are still in beta atm and we don't expect the developments to be done before the end of next month.
