Very simple - Bitstamp, MtGox, BTC have trading APIs.
I had a bot doing cross-exchange trading a few months ago, but than MtGox made the withdraws extremely slow and Bitcoins price started raising exponentially.
Yeah sure, you're right. The CEO is probably an alien. There is no way a Bulgarian company could see the majority of it's customers are from Russia and adapt by offering convenient payment methods. Never mind that Russia is the biggest country in Europe and it's heavily policing outgoing bank transfers.
IMHO China, Saudi Arabia, Japan, Abu-Dhabi, etc. can't be happy with US printing trillions of USD every year. They need a stable currency to keep their enourmous savings in, but the Fed monetary policy is eroding those savings. Bitcoins would be a perfect alternative. If governments start buying them, the total value can easily go > 1T.
Plus are you implying that hackers, like Bill Gates, Larry Page and Satoshi, can't possibly be (or deserve to be) ultra-rich?
IMHO it would be a huge mistake not to invest a few days worth of income in bitcoins . Most likely you'll loose them, but there's a reasonable chance you'll get 100x back in a few years. I invested $2500 in the summer of 2012 and just last week cached a small part to buy a Citroen C5 saloon.
