There are lot of ways to earn money online and one of them are through domain name flipping. It has a high earning potential but it also has the most risk. Flipping domain names are just like the traditional buy and sell system. You buy a domain name and the sell it at a much higher cost. The success depends on how catchy the domain is, think of a domain name that no one hasn't registered and the domain name should also be catchy and more relevant towards its categories. For example if you want to register a domain for investing or trading categories then look for investorsguide.info like that, usually .com domains cost from $8 to $20 and .info domains costs around $2 to $3. If the domain name is more catchy then buyer may buy your domain for double the price sometimes. The best sites you can sell your domain names are sedo and namepros.
