then you don't understand what makes cryptocurrency useful. It solves the wrong problems, which is why it's not useful (at least in its current form). You can't even do what you contend with cryptocurrencies right now, because as you admit they are trackable, by design. That's a very hard problem, and if you wanted to solve it, you certainly wouldn't start with a public ledger. The more you rely on trusted third parties, the less useful cryptocurrencies are since USD is far more stable and dominant. QED. This is exactly my point. You're trying to avoid trusted third parties when most of the world wants a trusted third party - as evidenced by thousands of years of economic systems which rely on it. Cryptocurrencies are full of interesting ideas, but they're also based on some wild assumptions which just don't match what most people use money for. Which is a shame as it'd be nice to see government grip over currencies undermined and a truly global currency which nobody controls emerge. I just don't think our current cryptocurrencies are heading in the right direction, or even starting from the right place to do that.
