I brought this up a long time ago, Advcash doesn't do CRS,︂ but they are merely an intermediary, their banking partners do, and each of which operates︃ within a CRS compliant nation.
They are kinda like Revolut/Wise, as in they either have︄ segregated or unsegregated accounts, but they have to ensure that records are kept and SAR's︅ are filed.
Though should add their USD card is actually Caribbean Dollars, so not entirely︆ sure how they route that around the backend.
I like that they use the Chinese︇ electric money system, I'd much rather hold Chinese currency also, even go so far as︈ to drop EUR/USD accounts and operate via their network.
