Whatever the name sells for in the future has absolutely no bearing on what the name is worth now. Whatever the buyer paid for Psychological.net, I can pretty much guarantee that he wouldn't be sell it for that anytime soon. So, that makes it a bad buy as far as domains go. If he turns it into a business and sells the BUSINESS in the future, it still doesn't make the name worth much today.
Some of you people still don't understand the concept. Generally, it goes like this..............The worse a name is, the more nonsense comments you will see about it having value "if developed". People continue to miss the point about valuation and they often confuse a business with a domain name. I even see it when huge companies are sold, some of which are publicly traded. You can usually count on a few people to start a thread saying something to the effect of: "Salesforce.com just sold for 400 million". What can I say? You don't get it, and some of you never will, but there are some new domainers who read this thread and the ones who deserve to have success will see through your line of bullshit when you guys continually muddy the waters when it comes to domain appraisals.
If nobody would pay anywhere near that price for a stand-alone name right now, it hardly makes that particular appraisal mean anything. If you owned a building and a plot of land then that building is worth the going rate for similar buildings and plots of land. You can figure out a reasonable range. And no two buildings or plots of land are exactly alike, are they? It really would be intellectually dishonest to say that that same building and land is worth what a successful restaurant at that location would be worth. That is the mistake that continually gets made here. The building and land are worth one thing. In the future, if someone buys the building and land and builds a successful business, then sells the business, that means he has sold a business that contains the building and land. The value is in the business at that point. Valuable land can make it easier to have a successful business, but if you create a good business on not so valuable land, then when you sell the business it is because the business is strong. It still doesn't make the low-value land prime real estate. If you build a great online business on a bad domain name, it will be your business skills that determine the value when you sell. It doesn't mean that your bad name is suddenly a good name.
It is not a hard concept to understand. To take it a little further. Manhattan buildings and land are worth more than small town buildings and land. That is the difference between dotcom and most of the other nonsense extensions. They are NOT the same. One space commands a premium because it is a more desirable space and more money is transacted there. There are certainly names that lend themselves to development, but you still want the prime time real estate if you are starting a business. When it comes to terrible or awkward names in bad extensions, it is the equivalent of saying that you are going to start selling luxury cars in the poorest town you can find. Good luck having success if you don't even understand basic economic ideas. If you don't understand what makes a name have value you should refrain from wild irrational appraisals that you would never pay yourself.
