Also taking note that it's far harder to hold with conviction back then compared to today.
Bitcoin has reached such high value that if you had invested before, you might see some growth and feel tempted to take it out. Even if you only had invested a small amount, anyone will be tempted to just take the money and spend it somewhere. This is why we need to focus on our goals and not let us get distracted.
But to answer your question: I don't have enough bitcoin; no one does.
Even the rich ones would want to own more bitcoin if they could. Knowing how much they can earn through bitcoin no one would want to even give at least 0.0001 of btc.
