I believe that even with the help of Bitcoin, a person cannot become too rich (a millionaire), because in order to get big profit from Bitcoin, you first need to invest a lot of capital. Of course, you can show the opinion that someday Bitcoin will reach $ 1 million, and a person could invest in Bitcoin either in 2010 or in 2016 or today in 2021, But in order to become a millionaire as a result, he needs to wait for more than one year and perhaps more than 10 years.
