Yeah, must be demo. Demo is the only way to "make" money. Also, forex industry needs a pin-up boy / girl, so he is lucky to be chosen. Forex industry is like hip-hop gangsta industry, where the elite who control the world need someone to push a product, so they choose a "star" and say "do drugs and you can be rich like them", or "trade forex and be rich like him". Lucky guy getting free ride from the elite.
That's a broker you want to stay away from. We call that "stop harvesting." That's a footprint of a market maker broker. Start looking for a real DMA/STP type of broker.
