Why do people buy numeric domains?
You simply need to check the historical sales for numeric domains.
why do people buy gold? because others covet it. Things only have value when someone else wants it.
What's the benefit of numeric domains?
to people who don't speak English much less write in English which is the dominant language on the internet as far as domains are concerned.
Numeric domains are the best option for both website owner and visitors.
so long as the numeric domains are short (2N/3N/4N) and memorable.
It is also a huge plus if the numbers are "lucky".
you'll need to know which ones are and avoid the unlucky ones.
It's funny to me how a logical business man would invest in a domain based on the supernatural belief of others.
There's even an auction in Saudi Arabia and in Hong Kong where people auction off their license places that have lucky numbers.
A plate with the single number 8 in Hong Kong sold for I think $10,000,000 USD or something like that.
Numeric domains have a practical use as well as a supernatural use (luck).
For example. Lucky.com? Is it lucky?
Or is 888.com lucky to the visitor?
or 777.com?
superstition permeates our world and our minds.
This is why we carry a rabbit's foot or hang a horseshoe above our doorways or walk the opposite direction when we see a black cat nearby lol or never open an umbrella indoors or eat long noodles during our birthdays for long life or blow a horn during New Years Eve to "ring in the New Year and maybe gets some luck."
You get my drift yea?
