Bonjour!
I have checked the web that you mentioned and I can manage the translation with no problem at all thanks to my 12 years in a French School (I have the French Baccalaureat)
In addition I´ve translated many criptocurrency papers, so I´m familiar with terms as Blockchain, Miners, Exchanges, Bitcoin, ICO
If you have any question, please feel free to contact me. I can translate around 2.000 to 2.200 words per day
Look forward to work on your project,
Kind Regards,
Larry
