Hi,
I have a 2 month old site: www.
livesteaua
.
com

Picking up like crazy
I am making $2-$2.50 per day with adsense, increasing around 10% steadily per day.

I am still marketing it
I am getting around 250 u/v per day, increasing 30-50 every 3 days

80% people bookmark

should I hold on to it or should I selll?
How much is something like this worth?

Thank You very much
