What if price suddenly goes up again next month and you won't be able to buy again? .
Imo the best option is to do nothing. Neither sell nor buy till market stabilizes.
It was a pure risk on my part. I just happened to be lucky that the market continued down afterwards. Part of it was knowing how much I'd panic if it got this low. I don't have the balls some people have

Nice work M'leev. Or you could actually even buy again now or soon if it goes a bit lower
