As more and more transactions happen through Phones and most of the scams happen on PC then you would imagine that the security for PC is more strict i dont go any specific statistic but its way more common on PC, personally i bought my burner iphone today so i will keep you updated, the thing is you have a burner phone with no traces to you and use yourself of public wifi and turn it off as fast as your done id guess its more secure on the phone as long as there is no surveillance.
