Tells me you have zero imagination and creativity.
This is pretty much where you're going wrong as a "domainer" .. it's certainly not unique to you .. MANY domainers have done it to some degree when starting .. you're using your own imagination to twist and turn and find cool ideas .. and then find cool domains for those ideas/concepts. But that is your downfall .. you're buying domains based on the fact end users will see your domain and then follow through with your idea / concept.
But the fact of the matter is that that strategy is backwards .. you need to find good names for business ideas that other people are ALREADY thinking of and planning to start-up.
Otherwise you're a developer .. with completely worthless unwanted domains UNLESS they are developed. Which is not domaining .. it's development. So sure if you build a great little site for wtf.cup it could certainly be worth something because of the developed content .. but as a stand alone domain it has virtually zero chance of ever being wanted by someone unless you pitch them on DEVELOPMENT (and *NOT* on the actual domain). Could it sell? Of course there's a small chance .. but appraisals are based on the risk/reward/costs of the name alone .. and on those merits alone wtf.cup falls far below what most of us would consider a worthwhile risk/investment.
The others are correct in that wft.cup is a bad domain .. you need to remember that the appraisal section has nothing to do with your imagined potential development .. it has to do with the realistic chance of somebody with an EXISTING business idea of finding and wanting your domain(s) for their business idea that they have already developed .. AND .. willing to pay a multiple to account for more than the costs of maintaining all of the other domains in your portfolio that don't sell in a year.
All that being said .. "Confidence Pays" actually does work for EXISTING businesses .. namely in the self-help industry. It isn't an amazing domain .. but it's good .. and much much MUCH more importantly .. it actually is a domain somebody might consider buying.
All these other "concepts" you have are cool .. and imaginative .. but you're putting the horse before the cart. Everyone will tell you it's a great idea or concept .. but when it comes time to investing or committing real time/energy you'll see most of these things never result in anything.
Particularly if you've never developed a website before, you lack the ability to truly gauge the time, resources, energy, and costs involved. All these combined effectively hold thousands of times more value than just the cost of the domain.
Based on your reactions you want us all to evaluate the value of your concept domains as if they were already completed projects .. so in your mind you want us to say that:
Your Domain(s) + Massive Energy = A valuable domain.
But the reality is that it is wrong to include all that development time/energy/cost when just evaluating the domain.
I'm not saying to stop dreaming and coming up with these huge multi-domain concepts .. but just realise that what you are talking about is not domaining .. and as such the honest truth is that more often than not people are going to tell you the domains are worthless .. because they are as domains alone. Whether they are worthwhile businesses is a completely different question .. but not one that should be reflected in a "domain" appraisal unless there is a very strong chance someone else will come up with the concept INDEPENDENTLY and come searching for your domain.
So many people you will contact for your ideas will tell you it's a good idea and bla bla bla .. but more often than not they are just being nice .. and have no real intention of following through with actual investment (or they might not even understand what is involved/required).
Again .. many of us pass through the same phase .. many many years ago long before I was a domainer I bought over a dozen similar domains with the same prefix _Music.com, _Money.com, _TV.com, etc etc ..
*BUT* I actually had a big site/community running on the music one and actually DID develop a couple of the others enough to justify buying them.
I strongly suggest you actually develop at least one domain based on your own "concepts" before going off and registering any more. For all I know you could indeed do great with it .. and then continue to acquire more and grow .. but again .. that is not domaining.
In terms of just domaining you're on the right track with Confidence Pays .. it's one of the better domains in this section .. which admittedly isn't saying much .. lol .. but it's a good buy at handreg .. and I would certainly pay $8 a year holding it .. the risk:reward is there for that domain.
