Most times as humans we feel more regret for the action we didn't take than the ones we took.
25 October 2011 he was happy that he didn't buy Bitcoin when it was $2.70, but comparing gap in price between then and now, is quite a lot to feel regretful.
Those were the old days, everyone has been thinking of buying Bitcoin too early but I don't think that the majority of us might still be holding it up to til' now if we're too early. It's very easy to say that on this phase because we see how successful Bitcoin is. But on the early days, it's most likely dark days for Bitcoin and full of FUD and doubts.
So in my own opinion, now is not too late to buy Bitcoin because it's still in it early days, and am quite positive that in 10 to 20 years time from now, Bitcoin has the capability of doing 10x to 15x of it current price, so it is best to act now that the opportunity is still there.
I agree. This is still early if someone is going to look forward for how many years in the future. People can also go back to this day when they've regret that they didn't buy whether today or by next year which is likely the bearish market.
