Patience, don't expect to get rich overnight

I've been on Binance for a week, and at first, I thought that if I bought a coin that showed -some% in red, when it rose to +some% in green, I would make money. However, I track my coins daily and see that if my overall funds decrease, they can drop a few dollars, and if they increase, my funds only rise a few cents. At this rate, it's likely that I will reach zero instead of making a profit. Can someone explain how the business works?
