Domain values have nothing to do with ad revenue, you have very few mega billion buck industries in the world, very few compared to how many words there are, so any one of them is a huge asset today, the reason is most of these industries have companies that spent billions creating a brand in that industry and the net is brandless, when someone goes to google or bing and types in insurance, all that money the big insurance companies spent is worthless, that's why so many people search for insurance and car insurance, a mega billion buck industry. Now that paid search has shown companies willing to fork over 50 to 100 bucks a click for these terms that means ownership and development of the main industry keyword.com makes all these assets huge assets. I would agree with OP that bitcoin.com is the gem and while i prefix are popular I'm not sure how they are valued, 25% or 10% or 5% of what the keyword.com is worth? Domain gurus would have a better idea. He says the big three TLD's are com/net/org, that's considered fact now in domain circles.
Now this is a bitcoin forum, so if you are going to find people interested in bitcoins and domains, this is the place, as well as domain forums probably. I would agree that any of those 18 domains he put out would all have development value to anyone into btc as a business.
Bitcoin is not a multi billion industry.
Domain value has a lot to do with ad revenue, there is a huge difference in just the domain, and that domain with ad revenue.
And, you and OP are probably the same person.
