You are not wrong, but the reward in terms of who sees more profit is not only the Ike who is convinced enough to hold for long; they enjoy the highest reward. To get convinced, you need to be early and also have the mind of conviction to hold.
Some were lucky to get involved early; some are enjoying some of the best profit today not because they know Bitcoin so well but out of luck. They somehow lost access to their holding, which restricted them from selling when their mates did, and later ran into its access when Bitcoin had already gained popularity, which contributed to their trust in Bitcoin.
Sure many who today celebrate high rewards are those who by luck restricted to there hold due to loss or misplacement to there phrase.
This could be an advantage that eventually made them get higher profit. I know of some people that bought Bitcoin then and where afraid to check and sell because of how others loss there funds, untill few years later they checked and it was a massive rewards.
Many that sold theirs earlier though it was some sought if schemes that would later collapse, so they invested and in a short time they sold it out Lossing confidence in the system that governs Bitcoin.
