The amount of Bitcoin needed to buy an iPhone has fallen from 162 BTC for the iPhone 4S to 0.015 BTC for the iPhone 18 Pro, according to crypto influencer El Super on X. The comparison puts the iPhone 17 at 0.007 BTC and the iPhone Duo, Apple’s first foldable phone, at approximately 0.025 BTC. If the 162 BTC once spent on an iPhone 4S had instead been held as Bitcoin, it would theoretically be enough to buy about 6,480 iPhone Duo units at that cited price.
