I'm not a technicals trader, for the most part, but what exactly do you mean when you say fundamentals?  I don't see where any cryptos have what I would call quantifiable fundamentals.

MAYBE with bitcoin you could look at things like user metrics, number of addresses, transactions.  But Ethereum has, well, nothing at all to evaluate.  From DASH on down on the coinmarketcap chart, you're talking about total market caps of $50 million and down.  There are no cash flows, no earnings, nothing fundamental to evaluate. 

All you've got are dev teams, technological differentiation, and other things that you can only hold OPINIONS about.

This shit is pretty much pure speculation, I'd say.
