The best time to plant a tree was 20 years ago. The second best time is now 
I cant understand this example but what I get out of it is to make your investments useable right now. You are not late as there is a saying, it is never too late. Time comes and go and things are just disappeared but the scenario is almost different in bitcoin case. You need to work hard and prices are going up. So ultimate profit for you in all cases. Better not to wait, buy now. . But I also agree that it is never late, not late to buy Bitcoin or for anything on that matter. When we look back in time, we can see how much Bitcoin has grown, and that is just interesting and nice thing to see. Imagine how much it will grow in future.
