It's risky but not the most one ... you know i will give you some examples .... if you trade real imported goods you invest big sum of money, order your shipment ... first you risk that the trader you bay from may freak you , if he is ok you get the risk of damage of goods for any reason consider an accident in the way ... if it's ok you get the risk of delay due to government papers , if it's ok you get the risk of selling the goods before their expiry date or in a certain period to earn your targeted profit ... then the last risk is after you sold all your goods and try to import new shipment you may find an increase in the foreign exchange rate for the currency you use then you also loose ... a long period of business and have all that risks ... so i don't think that forex is the highest risk trade only you need to adhere to safety strategies
