Most of the people who bought at $10 levels had already sold their holdings. It takes a lot of patience to keep holding over the years when price has been increasing so fast.

But there must be some people who had firm belief on the future of bitcoin and blockchain and they held their holdings till now. One example is winklevoss brothers. They held for quite long time and as a result they were in the top richest list in the world as well. That is how patience rewards you.
