I picked the lesser payout because I'm Canadian - there's no tax on my winnings. Add that the Canadian dollar is weaker to the USD... Going by
the website, any Canadian winner would cash out $1,135,982,701.40. ($820,600,000 USD)
I can say my brain can't... Math that many zeros.
USA tax payout is what, 30%? Even if you cash out, you're pretty much set for life.
