I try to tell people this. In a real world scenario btc may not work because of the slow transaction times. With that being said, btc will have to prove to the market it's capabilities outside of being a real good store of value down the road. Other coins are geared up to take it's position as the one crypto that can be used in a real world without the hindrance of slow transaction times.
