Lets see, 456976 x $10 (LLLL.com). That's gonna be some expensive renewal fees. Unless you have Chinese/Western premium or repeating letters, I don't see the point. I am ironic, of course.
Each LLLL.com is worth at least around $200. I don't see many end users for xokj.com which is not Chinese neither Western premium neither has repeating letters neither is pronounceable. However, it has stable floor price of around $200. By that logic it is OK to believe that each 6N.com could have stable floor price of $100.
I think floor price of $100 will not come immediately, but it is very reachable.
We might be witnessing of a new era of domaining! So many buyouts of short domains lately! This must mean something. At least, it will be called "short domain bubble" in the future and kids will earn about it in their schools. But whoever already took 6N.coms and similar domains get them for reg fee or slightly over reg fee and we almost don't have any risk of loosing money.
On the other side, this might be really a new era of domaining and 6N.coms and similar domains might become extremely liquid and with stable floor price above $100+. Who knows!
