Just do it when you feel that you're already in a win, don't be too greedy because that might just pass on without taking profits. I've seen you making threads about your portfolios that have dropped a lot and still you're unsure when to take profit. Well, if it's the time for you to take profit so that you can enjoy the patience that you have exerted on holding on it, maybe selling from 10%-50% quantity of your alts in profit are is fine while leaving the remaining of your holdings so that if it shoots more, then you're not left behind and you still have some holdings left.
