When the money was credited to my account I was given a 779 balance. So I assume 1000 coin balance is .01btc.
It is an odd way of denominating balance. So these are neither millibitcoins (mBTC) nor microbitcoins (bits), but something in between?
I would say this is also a flaw.
I've pointed out multiple flaws in the OPs site which is why I didn't complain when he sent me a few bucks. Pretty funny he's asking for it back, and I can't even wd discovering yet another flaw.
I think OP was just confused about what to do , because there are multiple post with different statements in which made him having more thinking on this matter.
But for me personally ? the amount Sent on you are not enough as payments about the Bugs you found , imagine if they will need to pay or conduct bug hunting for this matter? they will spent more than what they had sent you in which Fair for your Work without them asking you.
There are several Site that conduct this kind of event and if i remember it right Even the Famous FortuneJack had conducted Bug Hunting so their site will bug free when starts to re operate.
