There are some interesting tidbits in that article. One interesting part I noticed was this:
"But Casares noticed that every time he helped another one of his wealthy friends start buying Bitcoins, prices rose, suggesting to him that they were responsible for much of the increase. Over the course of March, the price of a single Bitcoin nearly tripled, to around $100"
All of the charts and trend analysis cannot predict some guy encouraging his wealthy friends to buy a lot of bitcoins. It also cannot account for someone who has a lot of bitcoins that needs to sell them all to pay for a house or yacht.
We seem to still be in the place where the price jumps by a lot all at once, which is likely these types of scenarios. But over time with more money on the exchanges hundreds of thousands of dollars will not be moving the price as much as it does right now.
