@38dbb9b0, that phrase "Gradually … then suddenly" is often used to describe the adoption curve of new technologies and innovations such as Bitcoin. It suggests that for a while, there may be a slow and steady uptake of the new technology, and then suddenly there is a rapid acceleration in adoption.

In the case of Bitcoin, it could be argued that we are currently in the "gradual" phase, where adoption is growing at a steady pace, but there are still many potential users who haven't yet started using it. However, the "sudden" phase may come when adoption reaches a tipping point, and suddenly there is a massive surge in adoption as more people begin to see the benefits of Bitcoin.

Of course, predicting exactly when this will happen is difficult, but it's an interesting concept to consider.
