Why it matters
Holding a domain costs money every year. A .com costs only a few dollars to renew, but a big portfolio adds up, and premium names can cost more. Holders weigh that carrying cost against the chance of a future sale. Sellers should know their holding cost before setting a floor. Buyers can use that cost in a negotiation: a long-held name with a low cost can be flexible on price. A common mistake is holding names with no buyer for years.
