Those who say that altcoins have patterns and trends are all beginners. The more you play, the more you'll realize that altcoins are completely unpredictable, solely dependent on the mood of the market makers. If they are happy today, altcoins will move in sync with the mainstream; if they are unhappy, they will go against the mainstream or fluctuate randomly. If you see someone claiming to find trends in altcoins, just block them. I acknowledge the mainstream, while altcoins are worthless.
