According to ChainCatcher, the Lloyds Auctions website shows that the official code domain name "XBT.com" for the Bitcoin international standard organization ISO has been launched for auction, with the auction ending on March 28 and a starting price of $2,798,917. The auction house's Chief Operating Officer, Lee Hames, speculated that Musk, Bezos, or even Trump might participate in the bidding.
"XBT" is the ISO 4217 currency code for Bitcoin, introduced around 2013, similar to gold (XAU) and silver (XAG). Kraken and BitMEX and other exchanges continue to use XBT for certain URLs and API endpoints, but switched to BTC during the last Bitcoin halving cycle.
