Rather than relying solely on "reported sales" of undeveloped (still) domain names between Usual Suspects™ and including those most heavily invested / influenced/ing in the "dot Mobey" perceptions of worth (which is now, rather clearly, being exposed with an lack of developed "ecosystem" and support and promotions from mTLD, IMHO) ... I judge value based on End user and legitimate corprorate acceptance and developments, IMHO. My experience and resulting sales over a number of years have lead me to the above opinion, conclusion!
As mentioned, there are many many threads on this subect here on #1 Namepros!

Many of those new and newer to domains, such as yourself, rely simply on what is being "reported as sold" / "domains du jour" ... BUT it is both sales -and- resulting developments and promotions (and traffic and sales and advertising revenue and ancillary monetizations, and even future resales) that comprise stronger components of value, in my judgement.

Just my two sense.
