However.

These currency codes, beginning with an X, are more consistent with ISO conventions than the current trend for BTC etc. In fact, BTC is reserved for Bhutan, IIRC. Codes beginning with X are more permissible for non-fiat and non-state-specific currencies, and thus perfect for cryptocurrencies like bitcoin (XBT), ripple (XRP), ven (XVN), etc. Feel free to keep referring to bitcoin as BTC if it is more convenient, but if bitcoin is to be accepted properly it will be represented as XBT, and Kraken is simply trying to be proactive in this respect in order to be a more professional exchange.
