 Now you find something very interesting here in eBay and Visa Those are two-sided markets meaning that they they in order for them to grow they need two type of users they need sellers and they need buyers in eBay and they need card holders and they need merchandising visa and This is why their metric is not in terms of users or card holders or buyers Because growing only buyers will not grow Okay, so and you don't want to have multiple growth metrics you have you want to have you want to have one growth metric Okay, so obviously eBay in order for you to grow if we eBay grows the GMV It means that he's growing both users both kind of users buyers and sellers and same thing for visa So this is why it's not always the case that the growth metrics is in terms of users or units that you sell or stuff like that
