RCG Markets takes less than one minute to verify documents, so we can say verification is instant. The only challenge i faced was that they only accept Passport & National ID card as means of verification.
However, my National ID Card here in Nigeria does not contain my date of birth so they rejected it and refused to verify my account, and i was notified in less than a minute.
RCG Markets should introduce Non-document verification where they just ask you for the document number and there will be no need to upload the doc. Brokers like FxPro have Non-document verification and it makes everything easier.
