As can easily be perceived in the comparative chart below, for the last year Bitcoin has both led the market on the way up and on the way down. That is to say that Bitcoin rallies first, and the rest follow (often outperforming, but that's another study). Likewise, Bitcoin turns bearish first, and then the rest follow in the downtrend. What's most interesting is that there's definitely a lag time that's worth noting.
“Duh” many will say, but it’s nice to have that kind of information quantified and documented. The big question is whether that will continue or not. My inclination is to think that it will for the foreseeable future. After all, Bitcoin is still THE household word. 😃
