How to add Bitcoin as currency for my website

Question

I have a website for shopping and I want to add Bitcoin as the currency for payment but when I try to implement this, I get IllegalArgumentException error. I am using java.util.Currency.getInstance("BTC") to set Bitcoin as currency.

How can I make this happen?

Answer 1

You cannot use BTC as the currency code for bitcoins under ISO 4217: (https://en.wikipedia.org/wiki/ISO_4217#Code_formation ). Unofficially, the wiki for ISO 4217 lists XBT (https://en.wikipedia.org/wiki/ISO_4217#Without_currency_code) as a currency code for bitcoins.

Locale.Builder b = new Locale.Builder();

b.setRegion("XB");

Locale xb = b.build();

Currency bitcoin = Currency.getInstance(xb);

Your currency.properties file will look like:

XB=XBT,000,3

Note that the parsing for java.util.Currencyonly handles a minor unit of 0-3:

Pattern propertiesPattern = Pattern.compile("([A-Z]{3})\\s*,\\s*(\\d{3})\\s*,\\s*([0-3])");
