Even ripple can beat the Bitcoin. It is up to us. But you can not change a lot of people's mind. Bitcoin is the reference coin. It is the God of blockchain. I think his lead will stay a bit longer than you think.
It will take about 50 years or more for any other cryptocurrency to eventually have the edge over Bitcoins because as they innovate more concepts to cryptocurrency the developers will also make sure that Bitcoin stays in the competition as well.
