I always think the hardest part about future trends is the companies that develop and market them will use their own branding. iWearables.com sounds like a brand to me so I can see someone wanting that, now I will agree I am not sure I could turn down low five figures like Kevin did, but then again, a lot more plays into it than just an offer, when you don't know anything really about a domainer except their username and some domains they own, you have no idea what that xx,xxx represents. Rick Schwartz could afford to turn down offers on ireport.com to get to $750,000. Personally I could not have turned down an initial $25,000, not because I did not like the name, I actually came up with a concept for ireport before CNN ever had it on their network.
The risk reward based on my financial situation would not work turning down $25,000. Mike Berkens once said he got an offer of $100,000 on Fashion Models.com and turned it down over a decade ago, he has not had another offer. He can sleep peacefully at night with his net worth and portfolio and rejecting $100,000, many cannot do that.
Its equivalent to the married guy with 3 kids in an office dealing with a douchebag boss and a single guy with no responsibility but himself. The single guy can tell the boss to go F off, the married guy with kids has to put up with a lot more and make undesirable decisions based on other factors.
