Does it make sense to believe that Bitcoin could one day be replaced by another cryptocurrency, that is, a cryptocurrency that really does make Bitcoin obsolete?
There is always some changes but it is very unrealistic if we talk about future. Bitcoin is a good coin and there is no coin that has a great features as bitcoin, however if another coin do really overcome bitcoin then the users will be cut in half because people thinks the new one is better but unsure of it cause lot of bitcoin users will stick to what they're used to, so it means that the coin doesn't really overcome bitcoin but it is just been a substitute instead.
That's only the case at the start. Everybody is afraid of embracing that is something new. Everybody wants the traditional way of things, that's why most people still stick to using fiat even when they know that bitcoin exists. Only the risk takers and the people that do their own research are the ones that adapt change at first. The new coin can be legit with no bugs at all, in other words, a perfect coin, but not everyone will still use it. People will still doubt the legitimacy of the coin and will only start using it when they saw that other people are using it.
That's the thing with adoption, honestly. People tend to look at other people first. If they are not doing it, then he will not do it as well. People always want to stick with the majority of the population so if the majority of the population is still using bitcoins, then other people will also continue using bitcoins even when there's a much better coin. This is the very reason why is growth is really really slow at first and then just sky rocket at some point.
