Cars.com as business (valued at $2.5 billion) was sold where the valuation of the
domain itself was reported as $872 million. If we ever get to see bitcoin dot com get sold, it will be done through a similar construction, because if you sell just the domain without a working business it's worth waaaay less.
Not in a hundred years would I expect a domain to fetch that much even though it was sold as a combi deal. This makes me question my prior valuation for Roger's domain, because a lot of factors do play a role.
Cars is easy to spell, most people in the world know what a cars are, regardless of the country they come from, and it is a booming industry even with how we're shifting towards cars running on electricity. Powerful domain.
Bitcoin is exactly the same. It's easy to spell, everyone knows what you're talking about, and its industry is booming as well, and it has a lot more potential in terms of growth. $50 million might even be conservative.
