what do you mean here is not Bitcoin but Gold (real Gold) that can be purchased on an application or site??  if yes.. advice from me, you should be careful and more thorough. in my country, many applications or sites appear to be providers of gold sales (we not accept the physical gold) but 85% is a scammer.  some are profitable because these digital gold traders offer first purchase discounts and purchase bonuses in large quantities.. again, you must be more careful..  you better buy Bitcoin than digital gold.
