I think that cryptocurrency markets are going to be more fluid in its adoption and abandoning of individual coins than traditional currency simply because of their nature. This, imo, is a good thing as it will force coins to continually evolve to provide better services, at a lower rate with quicker transaction times.
Edit: Fixed incorrect terminology.
Yeah. Bitcoin wont be around in the long term or at least it will lose its spot at the top
The question is do the forks of Bitcoin suffer from the same technological limitations at Bitcoin itself or did they redo the blockchain completely. If it is the former then all the forked Alts will go the way Bitcoin does. If it is the latter then the only reason to fork Bitcoin is for the name recognition and the inclusion of Bitcoin is not necessarily indicative of the veracity of the alt coin.
