Hope you can give him something good in return to find your unnotice bug
Yes, for a bug bounty.
Bug bounty compare to his winning, this is not enough. Usually bug bounty is only some amount and that is not much and i think that should give him at least half of the winning prize. 10 btc is good amount to win with recent price. And like i said before this is not his fault that he can bet that huge amount
I know, right? If he got paid for bug bounty, it's better than nothing. I doubt admin will pay him although for 5 btc (half from his winning amount).
Reached 10 btc from only with 1000 satoshis is a really awesome, also he did that on crash game. Maybe he can win lot too in bustabit.
Yes, actually it is true, rather than nothing OP should pay him this bounty. But until now there is no answer from OP and even the winners did not have problem with this, he just posted about his winning and gone without comeback. The winner should ask for this prize for the bounty at least to make sure that OP is really paying us or not. if the bounty is not yet been paid, i dont think that he is going to pay the rest later on
