One Blackjack hand for $10,000
I was staying in the Hard Rock casino in Las Vegas during March Madness in 2013 and watched a guy bet $10,000 on one hand of Blackjack.
The quality is kind of bad because of using an old phone to record. I have no idea why they allowed all of us to have our phones out but the dealer did not say anything as you can tell. This was in the high roller room right beside the sportsbook in Hard Rock Casino. I just happened to be walking by and heard a lot of commotion at this guy came in with a huge crew of people. Apparently he went to several different casinos and made one 10K bet.
