I've purchased hundreds of sites and sold 1 of them for good money. 

However looking at bitcoinwallet.com it has to be new money, not an investor.  First in their own news section they list the article stating that it sold for 250k.  I'm not sure I would do that.  Second the website is a disaster.  Unless an early whale, with no marketing, design or idea of what is going on luckily mined 100k btc's in 2011 is rolling in cash I don't see what they are doing.

But ... for those saying that these prices are ridiculous.  They are not.  Imagine buying bit in 2011 for .1 and someone asks price as .5 .. you would have said they were crazy asking that and now you would leverage your house, car, wife to buy as many as you could at that price.

This site, if btc goes mainstream in the next couple of years, could be work 1mm +.  If they put some coding behind hit and get some subscribers they could sell it for $4mm +

Or of course btc could die and it becomes worthless.

Over the last couple of months I've picked up a couple of .com's related to btc but they are few and far between.  I made up words and add bitcoin in it and they are taken.  The majority of them are owned by a couple of guys.  This isn't a bad thing it just forces new money to make up more clever names.
