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.
It is impossible to control the whole market and watch every change on it. In my opinion, traders must unite, create, probably, small communities, groups, where they can follow different altcoin changes. They can exchange the information to choose the better cryptocurrencies then and after, take the best decisions which cryptos they need to invest in.
