pretty lengthy and comprehensive article.... great job !!
i agree 100% with most of your views but i would also like to point out some ironies in not only your but virtually every analysis that i have seen so far...

i totally agree with you that we are at a very nascent stage of Crypto currency market and there will be massive changes that will come.
all these changes may not be positive!
i personally think several or rather most of the Crypto currencies will either be canabalised or absorbed by big corporates . (JP Morgan , Bank of Japan , uk , bank of america , mastercard and many more are already involved )

Several Cryptos may become obsolete or useless , there will be many frauds and hiccups (tangle tech of IOTA if proves its metal can completely make block chain tech obsolete) .... but at the end i am sure the market cap will be atleast 100X if not 1000X in next 5-10 years.
International monetary fund has predicted that in next 10 years around 10% of worlds GDP will be in form of Crypto currencies - in todays value this is more than 7 Trillion USD.

Now comes my biggest irony ( only my point of view and i can be totally wrong so..)
i personally think that the above statement is possible only if Crypto currencies come under regulation , these could be government regulation , international regulation or some other way of monitory regulation . but it is inevitable .
as the Crypto market grows government will take them seriously and sooner or later embrace but unfortunately regulate it in some or the other manner. (australia , south korea , china and russia are examples)

when this happen , Structured Money , international funds , mutual funds ,hedge funds and what not will start pouring money like crazy in crypto world and indeed 7+ trillion can not be ruled out. but the main beneficiary of these funds will be only those Cryptos that have some kind of regulations....unfortunately the exact thing that Satoshi nakamoto wanted to oppose when he introduced the thought of Bitcoin :)
