It was low yesterday, but it grew today. What is the reason? Is it because people started buying too much?
If you're talking about the prices of the cryptocurrencies going back up, there are many reasons. Some people just panic sell due to fear of losing their money. Others just sell to take out their profits when they make enough to satisfy them. But a big reason I think they were selling is to pay the bills, i.e. Christmas spending and getting ready to pay their taxes. The people who wait for the sellers to drop the markets start buying up because all the coins they want are considered on sale, so they are buying them up at very low prices. That makes the prices rise again.
