You're forgetting the large group of people who do not think about Bitcoin price at all.
You mean, those who will buy bitcoin for ideological reasons, at any price? They must all have all run out of money, because they are not buying for 255$, either.
I have a tradeable balance of $35,000. I'm not out money or even close. That doesn't even count fiat I have in my bank account. I'm just waiting for a little bit of retracement to maximally punish any weekend dumpers.
