LOL 10 BTC
Well the domain name is pretty decent as well as is the site value and I'm sure you put atleast 1/4 of that sum or more even into paying for SEO exposure but as for the website itself it's nothing more then the common cliche site with no unique idea's and just repetitive listings.
Might get an offer for 1 BTC if you are INCREDIBLY LUCKY and find someone who just wants the domain due to the site value but other than that you'd be lucky to get an offer for even 0.5 BTC i would say.
What you have sir is a site like what I developed
http://bitcoinegghead.com formally bitfilliates.com which bitfilliates i had up to a high "value" as well but by nothing more than just the work on it.
I tried to make my concept unique where this page is incredibly out of date and common plus not sure where your ranking ideas from but those sites wouldn't even be on my radar as top contendors.
Not trying to flame or even compare it to my own site but just trying to say this site is worth probably 1/4 of that site value of 4,00$ IF that.
Honestly that means nothing I could make a website in a certain niche and from everything I now understand about SEO and a certain website that offer's incredible ways to basically skip all the learning and lessons with tools as well. I could get a site up with a decent domain in any niche and have it worth that easily in a month now. I don't currently have the time for a solo project again though so.
Anyways.
