3character is a ref. only. It is usually on the low side of things.
NNN imo are harder to sale then a LLL , while rarer they are not as likely to be used for any significant purpose which makes end users harder to find. This topic has been asked before. Nothing has changed imo, they are rarer, harder to sale, not as easy to find end user yet still demand good money but do not sale for high 5 figs and 6 igs as LLL ocassionally do. Besides the obvious 777 666 888 000 800 etc .
LLL can be more risky than NNN though. We have seen several legit LLL names that have been turned over to TM owners recently... MBF.com and INC.mobi to name a couple off the top of my head.
