Selling now could easily be seen as a panic sell months down the line, I've made this mistake myself. Yes it's frustrating when you think "It's going to recover" and it doesn't, but it's basically sods law that if you sell after lots of contemplating then it'll be at the wrong moment. A lot of people are but patience is a virtue for those who don't. Yes I think it could touch $8k again, even $6k and lower, but it's looking increasing likely that this will be short-lived.
Sometimes you're better off HODLing and just sucking it up, it's only a sell if you sell low. If you really believe in crypto then keep buying the dips, not selling into them.
