I see that web is getting more and more competitive and it looks like almost nothing is left. Say if i start my site now (any site) what would be its value after 10yrs? Will there be any value? What do you predict in the future?
It depends on the domain name and topic. It also depends on sites rank. No real way of knowing price.
There is no way of knowing, unless it's a growing forum. For example if you have 2000 member forum and your growing 100 members a month. Then in 10 years it will be 15,000 members... But ofcourse maybe when your forum is 5000 members your will grow 200 members a month. So again it's hard to say, but interesting to think about.
if you think there is nothing left, you are soooooooooo wrong. New products come out daily, news never stops. The internet will be full and done when the world stops, until then there is unlimited opportunity.
