There seems to be a distinct lack of understanding of what a blockchain is.  It's pretty obvious what's going to happen.  Look at personal computers as an example - in the 80's there were literally hundreds of different home computers you could buy Commodore, Atari, Sinclair, Dragon, Apple, IBM, Aquarius, BBC - to name just a few.  Back then everyone was wondering which of these was actually going to take off, they all had their plus and minus points - then Microsoft happened, first with MSDos and then (more importantly) with Windows.  That was it, slowly at first all the other companies started to die off, even Apple were poised to die and were it not for Bill Gates bailing them out they'd have died back then and smartphones would probably still be ruled by Nokia.  Perhaps an easier comparison would be financial software - in the early 2000's businesses wanted more from their internal software, they used a database for HR functions, different software for office functions, different software for financial operations and absolutely none of it was compatible with the each other (much like today's crypto, all offering different shit but based on only one blockchain or database), there were thousands of companies supplying tens of thousands of software variants and then, almost out of the blue came SAP and Oracle Financials - Now every office has their core functions in one customised SAP or Oracle package.  Much like how the computer world now has PC or Apple - the office software is now dominated by SAP and Oracle. 

This same thing will happen to crypto.  There's no reason to have billions of different coins.  All you need is One Share - the share generates the coins - the coins support the tokens.  That's it!  One package that can do everything.  All the projects you see like Libry, Steem, Civic, XRP and any other you can think of can be combined into this simple set-up.  Coins are the currency, the share is well, a share and the tokens provide the for functionality.  As I see it, by 2020 all these coins will be replaced by possibly two - Humans love duality - Left wing/right wing, Red/Blue, Floyd vs Conor, Apple vs Microsoft, iOS vs Android, - of course there may remain a tiny handful of other coins, but come on, this is obvious isn't it?
