There i no investment that i " SAFE " like you mentioned.
Safe or Not Safe i up to your money management in the first place.
Any kind of business or investment involves some kind of RISKS, that' why they give you that warning before investing your money into any broker (Forex, commodities, stocks,...).
Nothing i easy or an autopilot money generator if not set up correctly by you & knowing the RISKS involved before start thinking about your gains / profits.
