Buying a domain like YRJF.com, for $3K... There is no real fundamentals in creating any content, or purpose. You are simply investing in a finite quantity in a controlled marketplace.
Some conspiracy theory
Perhaps there are no fundamentals but agreement. Thousands years ago people made an agreement that gold is money because it has many reasons to be: limited volume, easy to part, has some practical use, finally it is beautiful. Now a group of Chinese big guys creating something better than bitcoins. Digital gold - domains. And LLLL.com, LLL.com, LLLL.net and some other niches are perfect for this. Look:
Limited volume - yes
Easy to part- you can sell just one LLLL.com or one LLLL.net or LLLL.org, depends on how much money you need. You need a Ferrary? Sell LLL.com or a handful of LLLL.coms.
Has some practical use - you can sell it to a company that wants to own it and has enough desire and money.
It is beautiful. It is beautiful already because it is rare and you can even forward it to your facebook profile (like a ring on your finger), or you can have email account that everyone will be envy of (those who know its value).
Let's imagine hypothical situation when market (100k chips) is controled by 100 players owning 1000 domains each (or 10 players owning 10000 each, or 5 players owning 10000 each, and 50 players owning 1000) + 1 thousand of small domainers owning 10000.
Let's imagine unbelievable 5000$ per CP and crazy growth has finally stopped.
When it is LLLL.com-market it will be well known and there always will be new potential investors as well as thouse who want to finally sell. And number of potential investors will only grow. So it allows small 20% increase in price each year. Why not. If it stabilizes and shows steady and small increase - perfect situation. Why large owners need to sell their wealth? They already have house, Ferrari and investment that they don't want to ruin.
It can be broken only if a large number of domains are sold at once. I do remember a month ago we saw more than 100 CPs sold by one investor in public. And... Nothing happened. What would happen if 1000 CPs must be sold? Well we saw this too. Then one big guy come to another big guy and buys all his portfolio for 3 millions.
The market of CPs will never be flooded. Yes we will see yet corrections. Jump to 3000$ and then back to 2500$ or even 2000$, but big guys will always buy any number of CPs. This is what we saw all these last days.
Perhaps situation is out of control and price increase is too high. What would I do if I were very big share holder? I would sell some to smooth price increase and make a price correction. Price decreased? Buy them back. When market will be controlled buy small nubmer of main share holders they will manipulate it to maintain its steady growth and reputation like central banks should do. If they don't do that then we will see very sharp price increase and perhaps bubble burst.
But it is just conspirasy theory

But would be interesting who are main holders of these domains and if they have plan.
Sorry for that
