I never really why these people sell at a loss. It's easy to see the potential for bitcoin to get back to its previous high and even further, but people just need patience so I agree and think it's silly selling at a loss. I'd rather take the gamble and hold for mega profits in the future. These people will be kicking themselves if bitcoin goes to the moon again.
Emotion is an extraordinarily powerful thing. The best traders have conquered it and that's what they feed off in the markets. History is littered with people who gave up at the lowest moments.
The BTC market must feel like a gift from heaven to the pros because I'm sure it's many a holder's first dabble in any type of trading. They would be like lambs to the slaughter.
Temptation will kill so many holders that have a long ter mindset, we are ahead of so many lucrative bubbles that statistically, most (and I hope im not one of them) will sell way to early, when we think we sold at the top.
