I recently acquired Jack .is for a personal project, but I believe there may be potential to sell it. Although I've searched online, there is limited information available regarding .is TLD sales, especially for LLLL.is domains. Recently, Jack .art was sold for $10,700, but I don't anticipate Jack.is reaching a similar price point.
It's great that you acquired Jack.is for your personal project, and I understand your interest in potentially selling it. LLLL.is domains can be valuable, but as you mentioned, there is limited information available on sales of .is TLD domains. It's worth noting that the value of a domain depends on various factors such as its length, keyword relevance, and market demand.
Considering that Jack.art was sold for $10,700, it's possible that Jack.is could still fetch a significant price if marketed effectively to the right audience. If you're looking to sell it, you may want to consider reaching out to domain brokers or using online marketplace platforms to gauge interest and potential offers.
