I know its an individual thing, but if you are in an alt and it is pumping...when is the best time to sell? I feel as though every-time I am in a coin that starts to make some good gain I leave it to long to sell..Anyone else do that. I heard it is because of greed, we star imagining all things we can do with our new profits, but the longer we leave it the more chance of not making good profits. Does anyone have a good strategy for knowing when to sell?
