Why would even a permabull buy at 600, AFTER 400? If they are so bullish that they are looking for any buying opportunity, then they should have taken 400 which occurred BEFORE 600 (and would get them more coins also), or even 550 the day before. Instead they waited until after all that until the price was 600. Being a permabull doesn't mean you have to go out of your way to buy more expensive coins. That's not the behavior of a bull; that's the behavior of someone who panicking watching charts.
