I don't really see a reason as to why people post about this. The past is the past, let go of it. Nothing that you will ever be able to do now will ever place you in that same situation that you had 7 years ago. Even though it is a good thing to be thinking of, maybe we should focus more on the future and spend time in earning money through smart investments or through selling services.
History is actually well worth visiting, because it is a light on the path to the future. Not taking time to understand it and figuring out why certain things happened would amount to missing same and similar opportunities over and over again, because opportunities do come around and not once as some people choose to believe.
I used to have a few bitcoin 2 years ago that I sold as part of a panic when the price drastically fell one time. I regret my decision so much selling at such low price compared to the prices that we can see today. However, its not just bitcoin that this principal can be tied to, its basically any investment opportunity that eventually turned golden> Big tech companies that started out very small are just a few examples.
With what we have seen of Bitcoin especially how resilient it has become against all odd, we can right say, that today is yet another great opportunity to ride Bitcoin's trip to the moon as in couple of years from today, people are likely to look back and wished they took action today!
