I heard that the Elon Musk buys a large amount of Doge coins, so that's what makes a lot of it follow the Doge movement, for short term trades or investments. just like Tesla who bought bitcoin with a value of 1.5 billion USD. that's what makes bitcoin so high.
that's what makes people follow Elon. It is only natural for a popular person like Elon to get a surprising market response. he was in the spotlight with his company's rocketing product. after many people talked about it he immediately showed his interest in crypto. it made a huge adoption from the market.
