I don't get it: They say that they started using Bitcoin to help transfer money overseas, yet later in the article they talk of using TransferWise to move money abroad (which deals in pounds and dollars, not Bitcoin) If bitcoin's strength is meant to be its low cost for moving money around, how come even this Bitcoin peddlar cashes out back into fiat to move it?
