I completely agree on this,just look at bitcoin's trading volume and the transactions made.Yes,only a small percentage of people are using it regularly,but as bitcoin makes it's progress we will witness how it's slowly becoming a global factor.
That's true, the fact that it started with a small market and now it is steadily going up that is a good sign the it is becoming a global currency. In the near future we see a major improvement of the market of bitcoins as more people are continuously using it.
That is why traders are more active these days because they want to share and expand bitcoins reach to the fullest. And hoarding bitcoins only slows the movement of it.
