I agree to this, there are many people who hold bitcoin when its price was very low. I remember reading a post about a person owning 1700 bitcoin when its price was 2$ only. If you'll put that scenario on today's price, that person was already a millionaire! Same goes with other wise holder.
Yes. I do strongly agree that this is true. Clearly if that person really held onto his bitcoins, he surely can very well be very rich right now. And this also goes for others who really did hoodle. But the thing is, a lot has already sold their bitcoins back then because of all the fud spread which makes these few lucky people very few.
Now, if the investors are investors that invested only because of the butcoin hype on december on bitcoin's highest peaks, then too bad, they really have lost a lot of capital. I sure hope they didn't try to cut their losses amd sold their possesions. Because if they did, then too bad for them. They just made the second biggest mistake of their lives. And the first one was to ignore bitcoin back then.
