Let me reming people that this discussion started when someone asked for my idea of a good cryptocurrency. Well, among other things, a good cryptocurrency should be designed so that no one will be tempted to hoard it.
It already exists in the form of Freicoin. If I don't spend it it slowly eats itself. Er, it can fuck right off.
2% inflation goal is the current system. Which is failing (like Freicoin, lol!).
I predict this: On thursday, we will see Janet Yellen studder and come up with excuses (China? Europe? US employment? Another factor?) before she says it's too early to hike the rate. Just like a junkie saying that it's too early to pay for the drugs.
And just like the desperate junkie, she will hint that the rate will be hiked "very soon".
