And what is the maximum amount of winnings in this lottery?
2 324 000 000 USD (2.34 billion)

It is 7 000 000 ETH to be exact. so it all depends on the ETH price.
Where are these ETH from? Is this a weekly lottery or just "one" big lottery?
95% of money raised during the upcoming ICO will be put into the Jackpot. It's like almost all of it, what shocked me at the beggining.
Maximum ICO cap is 200k ETH, so I am curious how the jackpot can be 7Million ETH.
