Bitcoin Money!

The Money gem is a popular gem for Ruby. Ruby needs a gem like Money, for Bitcoin!

But BTC is unique, so this simple object should be unique.

Add this line to your application's Gemfile:

gem 'bitcoin-money'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bitcoin-money

Require it!

require 'btc'

Create from whichever unit of BTC.

a = BTC.new(0.012) 
b = BTC.from_mbtc(12)
c = BTC.from_satoshis(120000)
a == b # true
b == c # true
# a == b == c

Get value in any unit of BTC.

b # => #<Btc BTC:0.012 mBTC: 12.0 Satoshis: 120000.0>
b.mbtc # => BigDecimal.new('12.0')
b.satoshis # => BigDecimal.new('120000.0')
b.btc # => BigDecimal.new('0.012')

Perform operations.

a + b # == BTC.new(0.024)
a * a # == BTC.new(0.000144)
a / c # == BTC.new(1)
