This is the proof that you need to be upadated and have a great plan in every investment you do. For me I will set a target when the price value is still increasing but I already hit my target I already encash it. Because sometimes too much greed is the road to loss. And other strategy make sure that you are updated in every price vale movement.
The reason why I preferred to use exchange where you can set your order to sell or buy with the amount you desired then wait till it reach that and come back later. Sometimes it really worth the wait especially if it is a potential coin. You do not have to miss things by that.
