What is the difference between BTC and XBT?

Could you please clarify the distinction between BTC and XBT for me? I've heard both terms used interchangeably in the cryptocurrency world, but I'm not entirely sure what sets them apart. Is there a fundamental difference in their nature, usage, or functionality? I'm particularly interested in understanding how they're perceived by investors, traders, and the broader cryptocurrency community. Additionally, do they have any differences in terms of their price movements or adoption rates?
