Cryptocalypse, is there such word like that? oh wait I just made it by Myself 
even Earth has it's end or what we call apocalypse they say, but do you think crypto currency will have to? It's probably going to happen but not in our lifetime , cash was there for a long time (and still exists) then credit cards came (even If they aren't used in all countries till now) and now crypto currencies came and will take their place and after that , a new technology will come out... endless loop (until earth dies of course).
Maybe yes, maybe no. I believe that this crypto currency will take place or will be more usable than FIAT currency soon if government will not prohibit it(I hope not). Most of the trend application nowadays have no physical product to sell to but they are earning to it. Just like Uber, they don't have any taxi owned yet they got the biggest e-taxi transactions(I really don't know what they call it
).
