This is awesome and scary at the same time. A lot of huge companies are already trying to get a piece of the pie on large increments. Should there ever be a huge crash, we all know that these entities aren't as die-hard as most of us here, and would surely cut losses that'll send bitcoin into an even deeper pit.
Perhaps this is one of the chapters wherein bitcoin is really getting big and companies can no longer ignore bitcoin, and this is also that chapter wherein bitcoin is very fragile IMO.
Exactly, with bitcoin not having been tested yet if it can survive for a hundred years, it will definitely scare someone but you are also right that it is awesome because this means that we can test bitcoin and its capabilities to be used as a retirement fund. We can't do much about this but to hope for the best and continue hodling bitcoin until we are satisfied with the prices.
