But ever since that win, it kinda feels like I’m slowly giving the money back. Been losing around $10 a day for the past week. I’m still in profit, but honestly, I’m starting to lose the excitement. The game doesn’t feel the same anymore.
LOl, you're playing slots, you hit a jackpot and you're actually surprised this is happening?
What about the others that are drained every day with no jackpot so their losses even out your winnings and keep the RTP stable?

Slots are for having fun and wasting a bit of money now and there, try a new one, another one, gamble a few more $, no way you're going to achieve anything playing the same game every day, it's like a reverse world working schedule.
A normal scenario in any luck-based casino game. This is slots and such situation happens all the time. What can vary is how the player react afterwards. If he will withdraw the winnings, and call it a day or continue to play and consume again those winnings for his games.
