There's a bit of truth in your statement. Bitcoin is still far away from mainstream use. One of the best indications for that is the huge spread between the Bitcoin Investment Trust as a mainstream trading vehicle and the real BTC price. If even stock investors are seemingly unable to buy Bitcoin directly, we can assume that buying and holding real Bitcoin seems to be not simple enough for mainstream users - which btw. I find difficult to understand.

Irrespective of wild price fluctuations, usage of Bitcoin will be growing slowly but steadily. I don't think that Bitcoin will become mainstream overnight by some big company accepting it. Instead I think Bitcoin's growth will replicate its network structure: It will grow p2p, that means by personal recommendation as a solution to inflationary expropriation and a simple way to handle private purchases. That is also a more healthy way to grow, because the underlying technology can be refined to meet the demands of a growing user base.

So 2017 is not the year of the Bitcoin. Every year from now on is the year of the Bitcoin
