Money is not as wierd as anyone might guess. I work on a financial application, and money is almost always just a BigDecimal with the scale set to 2 (and stored in a database as a bigint type or equivalent). When its not, its just a higher scale (for say, compound daily interest on small amounts for a significant period of time).

How do you store Bitcoin?

Bitcoin uses fixed-width unsigned integers. The smallest unit is 10^-8 of 1 Bitcoin, which is represented as just 1.
