Bitcoin and oil have nothing in common-two different world, and oil Investors will not come to Bitcoin, this is wrong perception. Don't count on oil money he will stay in oil or in gold.
Bitcoin is very small player right now, and maybe in future can be pair with oil or with gold.
You can tie many things together and find a aspect that may look to be profitable. In Canada our whole being right now is Oil and how it
screws with the economy. So if Oil goes up,so does the economy and I see that coming around and altering bitcoin price.
Bitcoin may be small but it still ebbs and flows due to daily news in the economic sense.
Think the point about bringing in investors is more about people looking for different aspects they can take advantage of when other markets are looking suspect. You are right to state Oil and Gold people will stay in those markets but they could also dabble in bitcoin and that would increase the price alone.
