This is some fast talking [***] salesman trying to sell Oil Trades; Puts and Calls. They want you to put 2500.00 into some trades, and when you tell him " I don't have 2500.00; he says he will 'front' you the money until your Trades start profitting. Problem is, they don't ever start 'profitting', so if you fall for this kabuki dance, you deserve to lose any money the scammer takes from you.
