They are not lucky. They understand bitcoins value ahead of us. That is why they bought it and hold on it even when it was still almost no value. And they are now reaping the profits of it. It is not too late. Bitcoin can still grow more, and someday someone will say, they bought at 600 and now enjoying millions in profit.
I agree with you, they are not that lucky. But those people who can read the situation and take advantage of opportunities, even dare to risk investing in bitcoin at the time
