> (ie: if I borrow 100 BTC from you today, I only will have to repay you 75 BTC two months from now
Interest is almost* always non-negative. I'll only lend you those 100 BTC if you pay me something more than I'll have if I didn't lend them.
That makes a BTC based economy more prone to hoarding, and less prone to investing (what is clearly a bad thing), and also more prone to hoarding and less prone to spending (what economists think is a bad thing - I have no idea why).
* The exceptions to this rule are not systemic, normaly appearing in times of disruption. You can't base an economy on them.
