Are you going to translate your project into other languages? I think many people are not really familiar with the English and with the translator too uncomfortable. I'm sure it would attract a lot more people.
Translation of course will be useful but not mandatory. In such a project, and so everything is clear with the most minimal knowledge of English.
anyway ypu can find the whitepaper and the website of Egold in other languages already. Maybe un the future they will translate them to more languages
