Hmm.. some angles to consider
I always say, keep your best.. if this is your best name.. I say Keep it..
If you enjoy biking and would like to make a lifestyle with a biking site.. I say Keep it..
Opportunity cost - Consider the time developing a "roadbike" site as opposed to developing another type of Dot Mobi site, worth it to you?
How would you feel if you sold it for a couple hundred and Mobi really took off in the future?
The whole point is not to sell out to any negative vibes that may come to your life for your future as a result of an action today..
Whatever happens or not, though, have faith..
With this said.. if you do not really care about "biking" or it doesn't make you happy.. then consider selling it more..
If you have a watchlist of names and you would rather have 50 of them than this one.. then strongly consider selling it.. for obvious reasons..
I don't know your financial situation.. (If you have extra money anyway for your watchlist.. that makes a big difference here)
But off of instinct, with the limited information I see on your post, I'd say keep it..
The amount money (mid $XXX) isn't enough to make a significant difference for the longterm (unless you use it to buy 50 more).. the longterm difference to consider is how you would feel or not feel for a lifetime personally if you lost this domain at that price..
Do you enjoy "roadbike" in your life?
Kind Regards,
