we have very limited budget and time
Budget being limited is pretty much normal for a mediocre site but that being said the time to make your site into a perfect flaw free site should always be there. You cant run a site if you have no time to check on such huge flaw .
But our priorities are security, speed, functionality.
If security is your priority than you should have taken the action to take down the site to check on all the rounding issue on your site. The fact is that you are twisting your words and you dont actually take an extra measurement for the security because you are not protecting your investor nor your players because of this flaw
so they won't be able to select non profitable Payouts.
Is there even a "non profitable payout" ? As far as I know all payout is profitable because it gives your atleast 1.02 minimum in most site or do you actually mean that player wont be actually able to select a high multiplier like XXXX to prevent this things from happening? If this is so then you are not fixing anything, you are just limitating the ability for player to abuse your system which is a sign of bad move because people will see how incompetent you are
P.S : I could be wrong on this
This will be done next week. Until then site won't be closed as it was running with this bug for 1 year now and nobody complained about it, and some probably profited a lot. Won't even calculate.
Seriously this is another proof of how incompetent you are and as well as the site is. Also a proof that people should stay away from your site. It is not that nobody complained about it just that people doesnt even know what this means and they probably have no idea about this before because it is only happening in a specific multiplier
