Mass adoption this, mass adoption that... There's no clear path to mass adoption and it's not safe to assume that more adoption would help bitcoin become more valuable.
Mass adoption might lead to mass spending (assuming people will spend their coins more), which will result in an insanely high level of pressure on the price. At times where there is more supply than demand the price will definitely start diving in south direction.
Mass adoption will evolve naturally at the right time. Pushing it artificially makes no sense at all and can even result in network overload. What we need first and foremost is not mass adoption it is a secure and reliable Bitcoin network.
My vision is not of Bitcoin being used as a intermediary token to pay in fiat. That's like using horse to move a car. My vision is native Bitcoin payments. This will not be achieved via credit card interfaces. It will be achieved with people realizing that Bitcoin itself holds value and that they don't need an intermediary, because Bitcoin simply is money!
