I mean as the others have previously mentioned, it probably will be an external service, given that advcash does not have offices throughout the world (or maybe some super secret ones 😉 ). However, what I think would be interesting to know is:
1. How do they ensure you received the money?
2. How do you ensure that the money received is real, and if it is not, how do you resolve such an issue?
3. What is the legality of such measures? Not just from a KYC perspective, but the entire process. It seems rather sketchy.
