I have a 1 year old domain that is soon expiring, and my initial thought was to not renew and let it die. On the other hand, it might come in handy later as it is an aged domain, and it got to have some kind of value right? It has no backlinks or anything like that though. I also have some other expiring domains, how and where do I s e l l them? If I buy an expired domain for lets say xx amount of dollar, do I always have to pay that same amount each year? And what happens if the website/company that I bought the domain from all of a sudden shuts down? I assume I can't lose the domain, right?
