Now what he has in his mind is to regain it back coz he regretted it for being greedy. Though it is irrelevant to being bored, once he reach the point where he could control his emotions like he did in the past coz I've known him for being a gambler, for sure he'll get bored on that game and will try to look for a new one. It's just us who regrets that big amount to be honest.
Here in my country, due to gambling being illegal. People even in my area are inventing ways to gamble, they'd even play on some suspicious sites as long as they can bet, and mostly those bets not that expensive so even a regular person could bet and it's easier to understand, rather than betting at the online casinos in which it requires understanding and a bit costly, they'll just choose this even if it means they heavily rely on luck.
That friend of mine that I mentioned above also won last week on this small bets in our area and it's also quite big enough to be considered a small win. The only gamble that is legal in our country is those e-games that are legally registered and those lotteries. Other than that the rest is already not recognized.
