I experienced it firsthand. Usually I get a win after making two deposits. It is not a habit that I can be sure that even a small win can be obtained when making two deposits in one type of slot game that I play.
Today, I got a profit of around 25% of the amount of capital I deposited. I played on PG Soft for about 1 hour. The first and second deposits are the same amount. The total capital I played was around $205 but used fiat currency.
I lost my first deposit. While enjoying, adrenaline rises. I made a second deposit and played on the same slot but the bet amount was bigger than the first deposit. I won not in the free spins, but in the normal game.
Stop and withdraw some balance and return to normal activities.
Our brains are fantastic at creating narratives and stories around things that happened.
The important thing to know though, is that those stories and narrative don't have to be true for your brain to believe it.
That's how most of the superstitions were created, two independent events happened at the same time, say a black cat crossed and something bad happened. Then you see it again with another bad thing happening, and there it is, your brain now connected them, even though the cat has nothing to do with the other event... or does it?
