It will take significant time and effort to overtake Bitcoin's name recognition and first mover advantage. However, there's also an advantage to being a second mover that can adapt quickly to a changing environment... I doubt Bitcoin will be the supreme crypto-currency in a few years. It's just too implausible that Bitcoin is perfect enough as is, and/or the community will be able to implement any needed changes before its "competitors" take market share.
Regardless, it's a good time to be a cryptocurrency investor. We're still in 1996 in Dot Com Bubble time.
