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."
We all know what berries are, even as we know there are many exotic kinds of them we've never heard of but which are probably delicious and wonderful. Cloudberries?! Why yes, I'd love to try those!
Trading berries for something else of value is the most natural thing in the world. Even monkeys can be taught to save/gamble/prostitute in a sweet-snack based economy.

You don't trade runes for shit. They just sit there on rocks, being enigmatic. At most, nerds use runes in League of Legends to enhance/specialize video game characters.
Berries are fungible, runes are not.It's obvious which is the better name (hint: the one that's already working). Hint 2: If it ain't broke, don't fix it.
