Ironically, that's the mindset which keeps bitcoin from going higher.
When people reach a certain number in dollars, they dump their coins.
Only gold is strong enough to change this and even then most people would still prefer USD over gold. I know that's crazy, but if that wasn't the truth, nobody would be holding any USD in their bank accounts now.
A lot of people claim to make money this way, scalping the psychological lines at 10k and now the resistance at 12k. It all works well of course, until they get caught out by sudden rise, which is surely coming after all of this repeated rejections.
People just have a tie to USD, especially in countries with poor fiat regimes... that's the problem. Gold is still out of reach for most.
