Bitcoin currently has a clearly defined use case in which disruption is possible, the possibilities for Ethereum to enter the market are far less distinct. Ethereum benefits from the possibility of much greater eventual impact. Bitcoin is currently better positioned to leverage and be incorporated into innovations that occur across many industries, whereas Ethereum is trying to drive the innovations. Ethereum is at a greater risk of experiencing disruption, as their network is the major driver of value (while the Ether gas simply drives the network). This network which drives innovation opens up Ethereum to be disrupted by future entrants looking to build upon the existing framework. Bitcoin is largely safe from this threat of new entrants as Bitcoins explicit purpose of acting as a digital currency has been effectively accomplished, where future innovative networks can use Bitcoin as an underlying asset.
