Jideofor....while I can't speak for frostify (he's pretty creative btw), i see a lot of change coming in the way of "outbound" marketing in this industry.
For instance, I just hand registered 10 domains like BetheBall.com because i have a vision for an "end users" who might want them. I don't know who owns BetheBall.com, but whoever it is hasn't developed it, or has it for sale that I can tell
I'm sure you're aware that pretty much ALL sports involves a ball, and pretty much everyone on this earth knows it. Whether you're kicking a soccer ball, hitting a baseball, passing a football, shooting a basketball, or even playing pool, all of these sports involve a ball. Regardless whether it's players, fans, teachers/trainers, they're involved with these sports. If you can't imagine who might want to own the domain BetheBall.com for any of a variety of reasons, my suggestion is for naught
Looking at your Avitar jideofor, I see where you have have some pretty good acrobat "moves". Unfortunately BetheMove.com is taken, however domains like BetheJive.com and BetheStunt.com are available to register. I wouldn't recommend you buy them unless you can get your names in front of end users who might like them or see potential to monetize them....gymnastics and dance are a pretty big deal here in America, and I would look to sell BetheJive.com to someone involved in Dance and BetheStunt.com to someone involved in Gymnastics.
Finally, to buy domains like this and merely list them with the likes of Afternic, Flippa, Sedo, Uniregistry is a formula for failure imho. And this isn't to say you shouldn't do that, but you are much more likely to sell them if you "outbound" market them yourself or get someone to help you. Make Sense?
