Why has Bitcoin risen to $120.000? (1/3)

It has been a month since I explained to my mom and my sister what Bitcoin and Ethereum are last time. In just one month, the prices of Bitcoin and Ethereum coins have also undergone earth-shaking changes. Bitcoin once rose from more than 100,000 to 122,000. Although it fell later, it also stood firm at the position of more than 110,000. Ethereum soared all the way, from more than 2,400 to more than 3,800, and then stood firm at more than 3,600. Such changes make people wonder what factors will cause the leaders of these two cryptocurrencies to rise? After all, Bitcoin is not a company stock, and there is no difference between good and bad performance. So what is its target? Next, I will first explain the reasons for the rise of Bitcoin in three periods, and then use another period to talk about the reasons for the rise of Ethereum coins. On the one hand, I will answer my mother's questions and solve my questions, and on the other hand, I will let my sister understand the principles behind the rise of assets and increase her future decision-making and competitiveness.
