What I think and in my experience is that people will use Bitcoin when stability comes to the market.
What most people who is no-tech related, talking about Bitcoin is sooo overwhelming. Now imagine you tell them that the currency has variations every second and that in one month they can lose money, and in another month they can win up to 100% (like it happened two months ago)
When a small business can accept bitcoin, it has gained widespread popularity as a currency of the world. That is a prerequisite. Otherwise, that will not happen.
