Thanks for your reply.
I initially also thought about maybe high xxx, and up to 1k. However I have now started to believe it could be possibly worth a lot more.
1. I found out that there are many who use that name (or very similar ones) already.
2. The name has multiple great meanings, lux is a shorten for luxury, and fab for fabric (fabrication etc.) and I found some sellers/businesses are using the name with this meaning already.
Lux is also latin and mean light, splendour, enlightenment, glory, life. (I guess this is the origin of the word luxury). It is also "SI derived unit of illuminance and luminous emittance, measuring luminous flux per unit area." (wikipedia). I found out that a multibillion company is using "my name" with this meaning.
Fab is also a shorten for Fabulous.
So.. light, splendour, fabric(ation), luxury, fabulous etc. Great meaning and already many using the name or very similar ones).
3. An end user contacted me just about one week after I made it publicly for sale. Coincidence? maybe..
I guess this all points to potentially great value.. and not only now, but also in the future, meaning I probably do well to be extra patient.
