It is possible, yes but I don't think it will happen any time now. Bitcoin is the leading right now which is 10x the eths. Ethereum is really great, really great that it's always compared to bitcoin but still, eths is for fueling the ethereum blockchain that people use. It is a great project and a great place to invest your money but right now, Being happy that ethereum is number 2 is probably the best for now. One thing that ethereum lacks is the community based, the adoptations and the big investors in Bitcoin community. This is a very great gap between the two but still everything is possible but now is not probably the time.
