This isn't an investment, it's a bet. I make hundreds of bets every week, my results are not measured because one of my bets loses. Anyway, You can't say a bet is an investment, or I don't know what you're trying to say; you jargon is wrong with you. You're mixing apples and oranges.
Money spent in bet is literally fun money.
I try to make some money, like everyone who is playing those bets is. Sometimes we win, sometimes we lose.
One good thing about casinos such as whale are the promotions and contests. I have won several giveways promoted by Whale in the games and round board. This is a good way to make money without any risk. Sometimes I just spend the money in the casino, sometimes I just save the money.
