I guess buying domain names has become a hobby of mine. Well, an expensive one to enjoy right now but hopefully bringing generous ROI (return On Investment) in the future.

In other words, investing in good domains is like investing in the property market, with the difference that domain names only go up in value and not down. With the fast paces the Internet is running ahead and new websites jumping into the wild every day, I don’t see a logical reason why the graphic trajectory of domains prices should change its upward direction.

If you have a reason to believe domain names will start going down in value, I would love to hear it. I’d bee surprised if I received any reply about that.

My advice – buy, buy, buy! Now! Domains I thought were too long or ugly sounding years ago, now command prices I’ve never imagined one could ask …and get.

What is a good domain? Ideally a 4-5 letter .com domain. Well, these are long gone and the prices are just too much for an individual to access. Large corporate sharks normally operate in these cyberwaters where domains fetch prices in the region of tens of millions.
