I believe a power law acts differently from an exponential distribution. I think wealth distribution is commonly approximated by a Pareto distribution.
In your model, the exponential distribution is caused by the fact that you cannot go below zero; otherwise, it would be a normal distribution.
I don't agree with your opinion about laws against power laws, but that is another matter.
Well, if the price would be incorrectly set, then bots like this one would make money, which would in sufficient time cause the market to adapt and the average price would change so the bot doesn't work.
Yeah, because killing murderous dictators is helpful, and it doesn't matter that much who does it. In Europe, states aren't sacred – it is the freedom of people, and when people are freed, Europeans are happy even if it includes breaking the sovereignty of some terror state. I'm not saying I like Trump, but when he kills evil dictators, I can't complain. (There was 10k+ protesters killed in Iran recently)
There is huge potential hidden in Iran; it has always had a huge influence over the region and possibly the whole world.
