I don't know about any other person but personally, I've come to discover that winnings that are unexpected excites the most than the winnings that are expected, regardless of the amount of money involved.
Imo there’s no such thing as expected win for me in gambling since I consider my bets partly loss already. Most of my expected win especially on Blackjack always ended up on loss which is frustrating that’s why I never assume a win on my bets unless it already settled.
Answering the topic, Unexpected win always the exciting part since you have a huge money without looking forward on it. I just recently won around 800$ using a small amount of bankroll. I never thought to earn this money out of nowhere that’s why I can’t believe myself when I hit the big win.
Hitting a huge win while you are just casually playing is the most satisfying experience compared when you hit big win while you are expecting already that it will happened.
