$15k for bug is very interesting...
unfortunately I dont have a coding background (
15k??? wtf

sorry

Why are you apologizing? Indeed, for the error that the user finds, they give such an amount. Here is a quote from the official site: "For errors of the A type: up to $ 15,000"
oh gosh..bounty program............i thoud 15k for smt new

But getting such a reward is very difficult, you need to have certain skills and also find a critical error in the system.
Nobody can guarantee that there is a bug. May be there is no bugs. Person can check all the code but do not find a bug

Of course, there is such a possibility that there will be no such critical errors, but in any case, someone who understands programming will find some errors. And they are also paid and pretty good.
