How can you possibly fathom all crypto currency failing if Bitcoin does.
Have you not looked into ANY of the companies behind the 500+ coins? And what they are doing for the world?

Get your reading glasses on boys, you're in for a LONG read and a bit of a rude awakening.
Bitcoin is 1 currency. It doesn't have a whole lot to it, other than it was the first coin.

Now you look at something like Siacoin, they're going to put Google and Amazon cloud storage out of business.
Not only that, any coin using Ethereum's Smart Contract can put all realestate agents out of a job.

There's a bit more behind these digital numbers than meets the eye. They serve more of a purpose than to just trade around in the Market.
