Would you believe me if I told you a guy once bought nike.com for ten dollars and then sold it to Nike for $50,000. Well it did happen luckily it happened a few years ago so he was able to avoid being sued, but you too can become part of this money making idea of buying domains and then selling them. What you need to do is go to a place that sells domains like Go Daddy you then need to buy a domain such as a few months ago buying one saying survivingarecession.com, a couple of years ago no one would have cared but today that could go for big money. So you need to keep an eye out for domain titles and watch what is on the rise. Once there is a demand for that domain name you can sell that domain in a matter of different ways, one is that the company might consult you directly if they need it bad enough and pay you for it. Second you can list it on eBay, or even your own personal website or blog.
IS IT WORTH IT
Along with anything this will not come free. Go Daddy for instances has a price of about ten dollars per year for a domain name also with that if you don't renew your domain that name will go back up for sale. But if you end up getting the right one and selling that for fifty dollars that is a pretty good markup, I think most people will take a 500% markup. This is just like every other way that you can make money online, you need to keep your eyes open and see what is coming and if done right you can earn a lot of money. By that who would have thought that Bob Parsons the creator of GoDaddy.com who started his company in 1997 that only 12 years later, would have sold 30 million domains, so yes there is HUGE money that can be made online.
