Just sold all of my 0x at $1.77, I couldn't take it any more. When 1000% are reached I sell without flinching. After the correction, I can always buy more. Even if there wasn't a correction, I don't think that the ATH can be reached easily.
When are you selling? Do you also have a price where you can say: until now and no further?
Do you set a stop limit?
p.s. Now is the time to think about it, in my opinion.
