Newbie wondering about patterns.

I’ve noticed in the few crypto’s I’m watching that during normal stock trading hours, crypto’s price seem to go down. And after hours it goes up. I’m assuming that this is due to an addiction from traders who need to trade 24/7. I’m probably wrong, but I’ve had some success buying in mid afternoon and selling around midnight. I’m hoping this isn’t just luck. Is quick flipping crypto a viable option to increase wealth? I know it’s still risky but just wondering if others have the same experience. Most of the crypto I’m using has prices in the extreme fraction of a cent value. $10 bucks would give me half a million shares. But small fluctuations can lead to big gains if you invest enough.
