everybody who sold at 11k will bang their heads on the table.
It makes at the moment no sense to sell.
And do not come with "sell high and buy low" where is high and where is low? Nobody knows. IF this would be that easy why we r not all be billionaires already?
you're being too judgemental here.
What about people who're holding since bitcoin was <$1k and suddenly need some money?
you only loose if you sell lower than what you bought for. Not everyone plans on investing long, a crisp and quick little profit is enough for many.
Talking in general, you dont know about the sudden need of money people might be facing.
Most of the people suggesting to hold ignores the time value of money. I am not saying selling at $11k was a good move, i am just stating few generic cases.
