Which brings me to two questions the podcast left me with (i'm a developer, not an economy expert, so these might be really dumb questions):
1) is the hard cap really a good idea? Generally, currencies seem to lose value over time. Not to gain it. As the value can only increase, what's the incentive of spending coins now when they could be worth much, much more in two years.
2) being able to anonymously move coins between anonymous peers makes this really interesting for online payment (it's equivalent to paying in cash), but isn't this also the perfect solution for money laundering? Especially when combined with above fact that the value ever increases.
Still: something like this would really help in solving the micropayment problem, which exists to this day.
