indeed there are many alternative coins that have the potential to grow and develop, but to take the position of bitcoin is not possible alternative coins will always be under bitcoin, bitcoin as a benchmark price of each alternative coin they follow the bitcoin price movement to determine their price
In order to outdate the Bitcoin another cryptocurrency must have features and functions more responsive than the Bitcoin; this is impossible as after Bitcoin many coins had designed and all those coins are very low in value as compared to the Bitcoin, even its comparison with Bitcoin is also irrelevant. The Bitcoin can not be outdated and will never as this is the advantaged coin in the modern world and others will take a lot and long time to even survive in this market.
