Then you are just in for short and also to make quick profit. Holders don't time when to sell their holdings except it's a pump and dump coin.
indeed with a short-term trading method like that can provide a lot of profit but when doing this method at least you should be able to see how the conditions of the exchange as much as possible to trade when the conditions of the exchange place are a lot of activity or are having fast price movements because when conditions are not crowded then it will only make you wait too long.
