Interesting history on the name...used to be overall close to 10,000 on Alexa, and also per Alexa, 100% of the traffic is from Hong Kong.
The main concern is the AMOUNT of traffic. Whenever a website is taken offline, it is always in danger of losing traffic, and the questions is always how quickly. In the last 3 months, it's dropped 281,300 ranks down to 321,822 (so from about 40,000). That's quite a drop. Can you please provide data on the amount of uniques the name has gotten over the last 3 months?
The reason the revenue has gone up is 100% because of things you've done to increase the revenue, not the name itself increasing in traffic and/or revenue, so that's not a selling point in my opinion. Still, if you provide the data on the amount of visitors for the last 3 months, it will help people to understand how much longer the revenue may last. Backlinks disappear, return visitors disappear...that kind of traffic is not very solid when a name is parked.
