The billion max multiplier is basically just a marketing number, feels like they put it there to mses with your head. I just set auto at 3x now and walk away, it's way less exciting but at least I don't feel like an idiot after ten crashes in a row.
I remember that one save from Casillas in 2010 where the ball just wouldnt go in no matter what, his positioning was perfect all tournament. That kind of performance almost feels like a record in itself.
It always feels like the debate overshadows just how absurd both Messi and Ronaldo were at their peaks. I'd go with Messi simply becuase his playmaking added a dimension that the stats never fully capture.
if you're new definitely stick to the lower stakes tables first while you learn the flow, no shmae in that. also watch a few rounds before jumping in so you can see how the timer and betting controls work.
