For all intents it's a different system, the packets are encrypted, the right receiver hardware gives you vastly superior accuracy. There's civilian hardware which can use the packets without decrypting them for better accuracy, there's some patents on doing this amusingly.
I'm not really in this world, but you'd save more power by recycling aluminium cans (%5+ of US power consumption) than by killing off cryptocurrency mining.
The answer is a little unfortunate, even though things are said to be worth $xxxxM market cap, but the depth of the market is so shallow that the true value is near zero.
It's worthwhile to note that not a single once of the thousands of "ICO" things that have been launched in the last year have actually done anything of value. They all generate hype, raise money, and then give up and go to work on other things. It happens over and over again with no memory of the past failures, apparently.
That said I wouldn't fault you for believing that a lot of the $xM raised in x ICO just turned out to be largely the creator seeding the pot and a minority of other people buying into something "big". You could even take out a loan, there's nearly zero risk other than the operator of the ICO running with the scratch.
All obfuscation around a central controlling group that have the ability to reverse any transactions they don't like or negatively financially impact them, in other words.
The principle of Ethereum is that code is law, the "hacker" followed the law to the letter and acted in a prescribed manner. What's the crime here exactly?
