My first girlfriend really had her act together financially and got me setup on something like this 15 years ago. I thank her for it to this day, but this looks so much nicer as an app than my hand rolled Excel spreadsheets based on her advice!
All joking aside, if Bitcoin transaction rates are lower for merchants than traditional credit cards, I wonder if merchants will charge less (like they used to when paying for things in cash), and whether the CC companies will try to enforce price parity as in the past.
Actually, more importantly, merchants can now keep payments off the books for tax purposes, right? Forget the 2.5% transaction fees, that's chump change compared to a 35% savings of corporate income tax. Whoa.
