Now I’d like to ask you.. as a gambler, would you already be happy earning just 10% profit from your total bankroll?
Yes of course. Gambling is not easy to make profits and 10% profits is enough for me and it's better than losing it all. When you're greedy is when you will hardly have profits because even when you are in profits, you wouldn't be satisfied and you will continue to gamble and lose your profits and your capital at the same time.
Gambling is for fun and a game of luck, so 10% profits is more than enough for me, since I didn't do any hard work to earn it.
