Although Bitcoin is the first cryptocurrency, it does not mean that it will be the ultimate “winner” when confronted with newer technology.

However some things in its favour are:

-bitcoin is the original digital asset which makes it valuable
-there is no leader and therefore no way to stop or change the rules on it
-Bitcoin can be upgraded, meaning that any functionality that has been proven on an altcoin can eventually be added to Bitcoin
-bitcoin is in space, meaning that anyone with a computer and satellite dish can participate in it- doesn't rely on internet
-it has the most developers contributing to bitcoin - 3 times more than the second largest cryptocurrency
-so far bitcoin has survived 9 years and continues to grow
