It may not happening this soon but in future when the adoption finally happen changes will be done and Bitcoin will step down to give other currency a chance to prove that they are deserving to serve people inc rypto.
Actually eventhough we can agree in the word that there is no forever but still we can rely on it since even up till now the current state is pretty much solid and aslong as theirs a big whale and it included on the institutions and whales options we can rely that we will see bitcoins for more longer years.
but i don't think that theirs a coin will surpass the bitcoin since it is the face of cryptocurrency and I don't think if there are people who will take a risk for new one who claims that they will surpass the bitcoins standings.
