0,5 ETH for translating a BOOK (124 pages!) isn't a fair price at all, and more taking into account that now you charge 8$ per download.

I've been paid over $200 for the translation of other project's whitepapers (18-20 pages) that are free to download, and it is not an expensive translation. Here you are some examples of translation pricing: https://www.strakertranslations.com/translation-pricing/

We all know that those are new projects in their initial phases, and that most translators here are amateurs, but there are some limits and, imho, this is beyond all limits.

To all translators: get serious! your time and talent is precious.

To FrictionlessCoin: if you set a fair price for the translation or if you agree with a google translator translation let me know and I'll translate it into Spanish. Until that happens, good luck with the project.
