Just remember that the MMs are going to have a LOT of tricks up their sleeves. The first big run-up won't be the last. Look at the chart of the EVCC short-squeeze:
They will run this up, then try to walk it down and make everyone think they have covered and the squeeze is over. The people who have the strength to hold through some of these tricks will see even bigger gains.
Everyone will have to make their own decisions on when to sell, when it's right for them. But I hope everyone knows (and I will be doing my best to remind everyone) that the MMs have a lot of tricks up their sleeves to try to get people to sell themselves short and not get maximum profit.
