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.
But to answer your question: I don't have enough bitcoin; no one does.
That’s a straight answer, and that would answer in general. Yes, with the total cost of a single bitcoin, it’s difficult to accumulate even a single of it, that’s why it’s not surprising that majority of us do not have bitcoin at the present.
