I've heard about using a pin at the atm or simply just buying things and returning them for cash but the most i have ever swiped in one go is $160. So my real question is what's the true potential of a dump and the best method to make real cash off of dumps

Hey ive been trying for sometime and need a little advice. Can i swipe by using the chip jamming method with just track2 written on the magstripe or does it always need track1?
