Loolz bud, 1 million dollars is an outrageous amount to put into one bet, and this is assuming you even have such an amount of money, because I have been seeing and reading some of your posts and comments around this forum, and sorry to say but you don't seem to me, or pass out the impression like someone who owns such or more of such amount of money.

But then, I will try and give you the benefit of the doubt, by suggesting Stake and Sportsbet.io, this are casinos that I am sure can take such amount, but this is actually if they provide betting for the game in question, which I personally trust they should.
But again, I still do no think you have such an amount, though it's actually non of my  business whether you do or not.
