Ari Paul, CIO of BlockTower Capital, attributed the gains to a relief rally after a relatively uneventful split, as well as new investors buying bitcoin.
LOL. Spot on. I don't know why, but for some reason people were expecting some sort of "boom" during or after the split, like in the movies or something.

To be honest though, just like alot of people here, I was also expecting a dump. Atleast a slight dump, but no. The price didn't even bulge and stayed at the $2700 range.
Anyway, about that price surge, it just comes to show that price market analysis isn't everything. I think you can only predict it only to some certain extent, and I think news, updates, and public exposure has bigger impacts on the prices.
