I like "Rune". It's simple, easy to remember, and relatively easy to market. Also, I can imagine people actually using a cryptocurrency called "Rune" in the real world.
NO: "Your order comes to 4 Boolberries, ma'am."
YES: "Your order comes to 4 Runes, ma'am."
Google search:
RUNE = 11 million results.
Boolberry 32,400 - 95% relevant.
SEO will be taken care of. It will not be an issue. In fact, if RUNE wins, it will be in so many press releases, blogs and and articles in the future that the serps will completely change.
This community isn't use to marketing. The landscape is going to change dramatically.
