I'm creating a variation of a service that exists in one market and applying it to a whole new market. I'm pretty sure there's money to be made. I looked at keywords and competition. Very little competition and most direct match domains are available with the exception of the .c0m's for the main keywords. I contacted the owners of the .c0ms and they want tens of thousands for them so those are out of the question. Should I spend $500-$600 to buy all the related domains to protect myself from competition and get better traffic??
