Holding may be effective but not all the time. I do agree that patience is important but there are times when I regret that I didn't sell early because the price keep dipping until such time when the coin is just almost worthless because the developers of the coin don't inform the investors what is going on with the coin. Maybe my patience will pay off but I think this time it won't do. I just have to accept the fact that I have to sell at a loss. Patience does work most of the time though as long as you are firm with your decision.
