It will not end as of now.  It's only just starting. Given the fact it made a huge impact in the past year it is most likely not to end now. And yes most the coins have no value but that does not mean it is the end. There are many coins that still make a huge impact in the field and many are benefitting in cryptocurrencies. And it will grow more as it's popularity rises. So i think it's not the end for crypto.
