Regarding 6 character number domains, I know that pattern and certain numbers are important for value. Such as 556677.com or 677776..etc (Pinyin/Chips) But what about 6 character number and letter pattern domain combinations, such as (for example)? 99z99z.com 88bbmm.com 9988cc.com 1818zz.com 8888jj.com ....and patterns like those. in your opinion, worth investing in or can you see any value in those patterns? thanks!
