I have a question that you seasoned traders can maybe answer for me. As I am researching and considering jumping into this arena, I have noticed the term "portfolio" used. I understand what it means in this practice, however I am curious to learn, how long, on average, does the general practitioner, keep any specific domain name before dumping or allowing expiration if that is even a thing to do. In other words, if you buy a domain, and didn't manage to sell it in a year's time, do you renew? or do you allow it to expire? I mean I would think that if you did all the reasonable marketing and get it in front of as many potential buyers and you could and still didn't manage to sell it in a year, than it would be so valuable to you and would become more a liability to you financially. Thoughts???
