If this is true, I suspect that this is Elon Musk's first step to influence crypto to the world community and it will have a positive impact on the crypto market. if one influential person in the world enters the crypto world, then the market will also be carried away by the flow.
You should understand that this affection is short-term. His words make a great impact on certain coins, but they simply become hyped ones and in a month everything disappears. So I won't rely on his words and will continue choosing projects wisely.
If an influential person like Elon enters the crypto world it can have both positive and negative impacts. the negative impact is that the crypto market can be manipulated and the positive impact can increase the price of altcoins and provide profits for many people such as doge. but even so it is not that easy to control the crypto market because in the crypto market there are many whales.
