LOL why not? The bigger the pot the hyper the match.Really don't hope to see a money match in the hundreds of thousands.
And yeah it's like a cumulative thing. For example RayRay is putting up $1K while Noel Brown is backing him up with an additional $1K and Fanatiq is going to match that with his $2K. So that's a total of $4000 on the line $2000 from each side. From what I understand it's $500 minimum to add to the pot and it could reach 5 figures easily. The winner takes all the $4000 and it's up to him if he wants to give some money back if people supported him (like RayRay might give Noel $1000+ back and keep $3000-).
Then there are side bets to the match too which of course the players don't get in on.
