The money that FLIP gives you for inviting your contacts is not given to you immediately until your contact has used his, and he only has 7 days to use it because it expires after 7 days. If he doesn't spend it on you, they don't give you anything. El dinero que te da FLIP por invitar a tus contactos no te lo dan inmediatamente sino hasta que tu contacto haya usado el suyo, y solo tiene 7 días para usarlo porque se vence al cabo de 7 días. Sino lo gasta a ti no te dan nada. #Flip
