I'm sick of Americans. I know this thread is over ten years old now but with the US opening up for a lot of this type of stuff it seems the Americans are all going nuts for Kelly Criterions, trading, "futures", arbing, massive bets that'd get limited before you hit the last 0 in Europe, and generally being completely American.
I applaud the guys who are going to make a lot of cash out of this but I can't help but think that there's going to be a huge amount of them left potless.
Maybe it's just me, and I'm not down in the mud where "serious gamblers" are, but a lot of this sounds like people who don't realise the US is an immature market and the only reason they're getting away with any of it is because venture capitalist business models.
