i take .gov  ;) lol

According to https://support.google.com/webmasters/answer/1347922?hl=en

following domains are a good choice:

Generic Top Level Domains (gTLDs)
.aero
.biz
.cat
.com
.coop
.edu
.gov
.info
.int
.jobs
.mil
.mobi
.museum
.name
.net
.org
.pro
.tel
.travel

So if you're planning to setup a bitshares blog/content, keep it in mind.

Domain order for SEO/Google.com love:

.com/.net/.org/(.info/.biz/.mobi) all other top levels come with certain terms and are not that easy to register.

Note: Country codes are fine too, like .de to score at google.de, but they won't be as effective on the global rankings.
