etherium can do so many things bitcoin cannot. i think however that bitcoin has a longer shelf life. its not just that bitcoin was the first but that there are still so many who have no idea what cryptocurrency is and when they learn, bitcoin will come of first. i see people trading/buying with bitcoin and not with the other coins. i think etherium might actually surpass bitcoin in worth but bitcoin will always be the "gold" when trading crypto. that is my humble opinion anyways. great article!
