.btc domains are like regular website addresses, but instead of ending in .com or .net, they end in .btc. These domains are specifically for websites that are related to the cryptocurrency called Bitcoin. Bitcoin is a type of digital money that you can use to buy and sell things online. So if someone has a website with a .btc domain, it's probably a place where you can learn more about Bitcoin or use it to make purchases.
