No lies, with such an amount used to stake, I'd definitely be tensed. Like, what the hell!! It's normal to feel this anxiousness when your game is going on and if it were possible to join those playing on the field so you can get your desired result, you'd do it. I'm glad that there's audacious gamblers out there but at the same time, it's important to use your head and do it responsibly.
To some people in developed world the amount should be loses than $10 in my country's currency which is not a big but for people like us in developing nations, this is big risk. The amount is approximately my one month gambling budget so there would be a lot of tension. I don't think I would hesitate to case out if I had the opportunity. I assume that there are many people who can take the risk but I cannot because I take advantage of any little situation to cash out.
If a good P2P exchange rate is used which is around $1597 right now, that would be about $65.42 naira. He used 12000 naira to stake the bet. If you deduct that from the amount won, only $57.91 will remain. In my country which the OP comes from, we can say it is a big amount of money, but not that too big in a way we can call it big.
Such an amount will be enough to take care of a bachelor for a few days depending on how he spends. The highest amount I have ever won was about $37, and it was one of the happiest days in my life.
