Over 10K always.....Felt a lot safer back in the day then now. Not uncommon 10 years ago to have 50-75K combined. Not any more though. Just wouldn't feel safe now for some reason.
You can often wager $100,000 on Pinnacle online. I think I've see $200,000 on some games. $500,000 or $1m on the Superbowl, Worldcup final, etc would not surprise me.
All far far outside my league, but that's what's available.
