Those people that left when the price went down to $250 probably they went back already. This is how the crypto currency moves and it's like a gamble for all of the traders. Those people who exited earlier sold their bitcoins when the price was still at the 3 digit line and saw the price now for sure they are crying and blaming themselves.
It's for sure they came back after dropping their own bitcoins and selling it with a very low price. It's one of the problem of the weak traders, they are not believing on what they've got. They didn't have any plans to hold for a long time and always looking for a daily profit and they feel sorry right now because of that wrong decision.
