Of course, winning $6 from betting $10 doesn't make you happy. But in a case like
this
it surely does.

Oh wow, gambling is just so uncertain. Imagine if you had staked that game with 1 litecoin and won; your cash out would have been really massive. I know you never felt so happy about that one. You probably asked yourself why you never increased the stake, but that's just how gambling can be. I believe you already know since you have a lot of experience, just as you have said.
I have also staked a game with $0.005 and won $50. I know I felt like, "Oh, why did I not just stake that game with $5?" But it was risky because the probability of even winning that game was only 0.1%, and it shocked the hell out of me. For me, who often prefers sports, there are usually some games you are so confident that you will enter, but those kinds of games are likely to get busted, while the ones you never expected to win will be where your luck lies. Winning gives joy, but especially when you win big,
