I have a wallet with them and they blocked my withdraw capability because KYC.
I'm spanish and after several months requesting various information, they ended requesting me bills in english laguage, but Í'm spanish and live in spain, so i can't provide any document in english.
They keep blocking my funds and asking for information I can't provide.
They will ask you for ID card, driver license, photos of you holding documents and your smartphone showing your account at the same time and so on.
