Although both WorldFirst and CurrencyFair are well-proven, regulated and effective money transfer companies, with bank-beating rates and fees, and much quicker delivery, than banks. However, there are some distinctive differences between the two. First and foremost, CurrencyFair is the only solution of the two available for the USA residents. On top of that, the unique peer-to-peer system allowing the lowest exchange rates possible, and a nominal minimum limit make CurrencyFair a better choice between the two.
