A few days ago, I lost almost $1k in less than 30 minutes, in that time I wagered maybe $2k...
That's sad. I was in good profit when I had around $7k wagered here and now it's a loss for me. It happens. Other day, if I'm correct, I got a FS after almost 800 spins and the reward was $21 ($1 based bet). Lol.
You can't win all the time.
The most important thing is to responsibly have fun all the way.
