Actually IMO, everyone who's in crypto, already speaks English, more or less. So a lot of the translations are made out of prestige (or the teams have nowhere to spen their coins). The ROCO team spent some $ for German and Spanish translations out of prestige too, as far as I was told. Not by a bounty, because they have no means to check out if that's google translate or not, through some friends. And they also made a Japanese translation, because it was a surprise for them that many Japanese ppl communicate via google translate on Discord and other media, so they wanted to care for them.

I'm the Russian speaking moderator of the team right now, in some time I will make the translaton.
