And if we are to worry about paper losses, the skeptics have more to lose than their untarnished egos. For example, you have been around these parts since December of last year, you've had plenty of time to accumulate some bitcoins for sub $1000/$600/$300 prices. Your lack of buying over the past year means you've forgone the chance to reap the benefits of a sudden bubble to say $6k. That's a 10x increase in paper gains you are betting on not happening. Which I would guess would have more impact to your life than the loss of a couple million would to the Draper family. Fear of missing out is as good a reason as any to try to influence the price down for a skeptic.
I am not sure I understand the logic. "I may have an oportunity to make more than 1000% ROI in the near future, but since I did not bet on that opportunity before, I will try to prevent that opportunity from arising."
By the way, note that my strategy -- NOT buying a single satoshi -- has put me in a much better position, vis a vis that fabulous possible opportunity, than all those who went "all in" since last November, when I first learned of bitcoin. In the unlikely chance that I decide to invest now, I will get twice as much return on the dollar than those who bought in January and have been hodling since then.
I think you understand the logic fine and are being a little facetious, but is quite believable for trolls/skeptics try and prevent a rise in price.
Trolls like to make comments like "How will you look your family in the eyes when you have to tell them you lost all our money when Bitcoin crashed."
They don't want that type of comment applied to them. "How will you look your family in the eyes and tell them you knew about Bitcoins when they were worth under $1000, now that they are worth $100k. We could have been set for life, and not left with all this worthless fiat".
Trolls/skeptics live with that fear everyday. They want see price go down to make them fell good that they made the right call. No one wants to be on the wrong side of history.
P.S. Invest now, its fun.
