Ask HN: How much is yourname.com worth it to you?

I've received an email from a human (sent something related to the content of my website) asking me to sell my domain name (alextoussaint.com) for $2k.

I'm using it as a personal page and for emails. I don't need that money but getting a 200x ROI on a $10 investment made a year ago seems appealing. But, I fear to regret it in the future (10-20 years from now) where .com's will be very scarce.

So, how much do you think this domain's worth it? Have you already regretted selling one?
