There are many parameters besides traffic that determines the value of a domain name. Some are:
- What is the extension
- Business niche of the domain
- Competition in that niche
- Advertising cost for that niche
- Advertising revenue from adverts placed for that niche
- Geographical source of the traffic
- ... what type of typo is it will also affect the value of the domain
And these are just a few.
I will ask you a similar type of question. The piece of string I am holding, which you cannot see, well how long is it?
(No that was not said in sarcasm, I simply wanted to show how knowing next to nothing that no reasonable answer can be given to your question.)
