I don't have enough bitcoin; in fact, what I hold might even be someone's daily spending, and its worth is not even up to what I could be proud of right now.
To be honest it's easy to see riches these people could've made just by holding the hundreds of bitcoin they had back then. But the question is, which of them actually held the coins until today? Also taking note that it's far harder to hold with conviction back then compared to today.
Those who were still into bitcoin from that time until now might still be holding, or some might have sold out during the last bull run that took bitcon to $60k+ and above, which was the first time that price was reached.
