wasn't a big deal...
It is indeed not something that will make the user to get rich overnight however the rounding issues are giving player
an edge over 30 % and that is indeed a big deal .Also that considering your site has an investment feature than it means investor is getting -EV which serves as a bad reputation for your site.
Your action of being hostile towards someone who give you a heads up also disgraced dooglus' calculation about this issue also is a bad publicity for your site and now people will think twice about investing on your site. In other words you have dug your own grave and it will be just a matter of time before more people read this thread
P.S : are you going to give Substrata the bounty for finding this flaw of your site?
Hostile? We offered him bounty, but he was to greedy to take it. We are small site and don't have huge profit, so we can't afford to reward everyone that says he found a bug, and doesn't want to tell us about it if we don't pay....
For this 32% issue or whatever it is impossible to reproduce, so you are wrong at some point, not sure where.
