Bitcoin has a unique position in the crypto currency world. Not only does it have the advantage of massive first mover, but it also has some elements that other digital currencies cannot achieve.

First, Bitcoin has no leader. No one can be thrown in jail if the currency starts to threaten the traditional currency.

Second, Bitcoin is by far the most censorship-resistant currency. If this network doesn't want a change to happen, then the change won't happen. This is one of Bitcoin's most powerful qualities.

Lastly, Bitcoin is completely decentralized. Thanks in large part to its organic growth and this growth is something that can no longer be achieved as people plunge into various projects to enrich themselves. Bitcoin evolved into the global giant it is now under the radar. Bitcoin appears only when it is ready.
