Back when the dot PAGE tld was released a few years ago, I was the first person to register 404.page because I thought it was super nerdy since "404" is a developer term and I'm a web developer. It is an HTTP status code that means "Page Not Found". The original cost to register this domain on release day was $250. Since then, I've renewed it twice at a rate of $167 per year. Thus, I have $584 invested in this domain. I haven't done much in terms of outbounding to promote it because I enjoyed owning it for the period of time I did. It was my "flex" domain and just pointed at my portfolio and resume. I have received a couple of offers in the time I owned it, but they were very underwhelming until last week when I received an offer for $600 through my Dan.com lander. This would have left me with a profit of like $20, so I kindly explained to the buyer the situation and I was upfront about the premium renewal cost and told him how much I had invested in the domain. I gave him a counter offer of $850, which would give me a profit margin of $200 more or less. My thinking is, if I didn't sell it now, I would never be able to sell it because every year I would be increasing the BIN price to offset the premium renewal. To my surprise, he accepted my offer of $850 and I had Dan.com pay me through Bitcoin, so in the long run, the value I received will only increase since I'm not withdrawing it anytime soon. After Dan.com fees, I walked away with the USD equivalent of $773, which I'm satisfied with.
