Bitcoin issue

[php5developer]

The Bitcoin currency ID in xe.com is XBT, while in google it is BTC. So, from time to time I got error: "failed to parse response from {rate provider}". Thank you.

Is there any ISO standard for this?

Actually no. Because most of countries do not consider Bitcoin as currency. As I see, now you do not use GoogleCurrencyRateRequest class to fetch rates from Google. Maybe in the future you will return to its use. All in all, I compared to list of supported currencies by xe.com and www.google.com/finance/converter And what I found:

Not support by xe.com: Chilean Unit of Account (UF) (CLF) Not support by xe.com: CNH (CNH) Not supported by xe.com: PKG (PKG) Not supported by xe.com: Zimbabwean Dollar (2009) (ZWL) Not supported by xe.com: Zambian Kwacha (1968–2012) (ZMK)
