It is anybody's guess.  But if it is as it is now for many more years I would wonder what it was for.  My opinion is that the big banks are working at this very minute on their own crypto and it's a race to see who is the first one out.  I did read that it is possible in years to come for a few cryptos to exist and people will have a choice of what to use.  Like currencies are now with dollars euros  and so on.
