My opinion here.
agree (mostly) and great grafixs!
RE: the top10
yes BTC is the only fiat to crypto tool of importance
but I think LTC and XRP are hard embedded as markets #2 & #3
so I see a strong relationship with BTC and 2 dozen ALTs
after that the other 500 cryptos are better served working with NOT bitcoin markets
LTC really has not created any solid markets for ALTs but hold title #1 crypto trading pair to BTC
XRP has the cryptsy market but that just might disappear with cryptsy and has failed to expand eXchange adoption
[Dash could replace XRP for the functional low inflation high volume coin]
Doge stands to capture 100s of micro crypto markets and thus become useful!
Doge also popular with the average person.
BTC has been captured by higher market players and is risky business for normal everyday folks.
ETH .. true .. closed off and likely headed for a long bear drift south.
But holds enough high ground to retain top 5 position. Yet BTS and NXT and XCP and OMNI and XEM have attached assets. Not true for ETH.
But big money is backing the project.
TOP 5
BTC, xrp, LTC, eth, DOGE
there are the digital 'currencies' ... constant liquidity required
Every one else is a digital 'project' and must produce a product other than a trading coin

addendum;
PPC, NAME, XPM, and perhaps XMR are solidified at Tier2 level digital 'currencies'. Granted NAME could loss this title if the project is still stagnant by 2017.
Tier3 players included BLK, the crypto 2.0 group, Nova, DGB, FTC, VTC.
And there are many contenders still stuck under $500k, that offer differing currency designs that could in years to come move to top10 rankings.
