The number one rule is real estate is: Location, Location, and Location. With Internet properties it is not that much different. Hot places are valuable and people are bidding for them for that reason.
Naturally, ther are difference as domains and websites are virtual assets, which nevertheless have become real assets because they can earn real revenue and profits.
The number that have been paid for doamisn in the past 15 years confirm this. IN 2015, for example, the domain vegas.com sold for a proud $ 35 million. Insurance related doamsin have sold for similar prices in the past. With billions of people surfing the Web on desktop and mobile devices, and that 24 hours a day, Internet traffic to top websites will remain very strong and advertsing budgets will go into the properties that people visit most. Making money with the right asset is therefore a very real possibilty.
