Чем Вас не устраивает современный материал, где сравниваются показатели в документах Минюста Чехии и на сайте Worldcore? Приводится перевод отчета Ernst&Yang и ссылка на кошелёк Эфира Worldcore. Всё в открытом доступе.

Отзывов для анализа предостаточно, при том более чем годичной давности:

• Worldcore - Scammed me out of more than $200
• Worldcore is some kind of an scam to collect interest on your money and exorbitant fees for doing basically nothing.
• Also have had money frozen and no resolution in site. Company seems new with little available information on the web about them. A lot of the available information seems to be fake.
• This company is straight up fraud. They collect your documents, claim your account is verified but as soon as you wire in any significant amount of money they freeze your account claiming that they need to "verify" things due to "money laundering".
