I've been throwing this chart around for quite some time now:
http://coinmarketcap.com/charts/#btc-percentageI was under the assumption, that the recurring pattern of Alts spiking, then quickly retract and go into a long bear market, would eventually reoccur. I still believe this will happen at some point, but now it looks like the chart tells another story: BTCs percentage has dropped lower than the chart would indicate.
I am not sure what to make of it. It may well be possible, that, even more than before, we need to look at single Alts, like Ethereum and Ripple, which make up a big proportion of the 40% cap. For example, it may well be, that while the other Alts go into the predicted bear market, Ethereum manages to keep its momentum.
I'd be very interested to read some opinions on that matter.
