I mean, ch.at is a incredible domain hack. But not sure it's worth millions. If it was ch.com could get mid six figures and up. But either way absolutely amazing domain.

There was a time that I owned a one letter domain with a two letter country code.

The cost was about 600 USD and was fun, but problematic as it failed to be accepted as valid email address on many websites.

unless they are .com, nobody cares.

I wonder if a 1B model could be close to free to host. That's an eventuality, but I wonder how long it'll take for that to be real.
