I don't agree on this one except if you are doing trades or day trading. To me, I only buy potential altcoins so I have no reason to rush buying and selling them because I only picture the endgame. And another one is that none has that ability to have the perfect timing of making successful trades,
Yeah, its better to choose some good altcoins rather than execute fast trading. Its to hassle when you proceed on that thing you can't proceed another activities in your life that might you happy as well. However, we have different perception on cryptos, someone contend in just holding a coin in long time and someone prepare by making fast trading that seem you do day trading method.
