Totally agree.Have done the same as I fear the greed factor could cost me without a few presets. Plus age, timelines, health & goals, etc... come into play. For obvious reasons, I can't say what I would do if I were someone else. IMHO, the hyper run up fades by the day.(still possible) .This stock has so much potential & so many moving parts that I do not believe that I could sell ever sell without FOMO. That is reason enough for me to believe that it will always (or for the for-seeable future) be a fav for traders & a target for shorts. If you like action, this is definitely a stock to be in. For the good news,there are probably 10,000 stocks that you are more likely to lose money investing in, if you are willing to sell after a 50 % gain(imho).
