I am not sure about the millionaire status. But you can make a good amount of money depending on how intelligently and how dedicatedly you trade or invest in crypto. I have heard that people have gained a lot with the rise of Bitcoin because they invested in it at the right time. So, you need great timing, learning, and strategy to gain profits in cryptocurrency. Maybe one day, the millionaire status will come true for every crypto investor.
I wouldn't say everyday but every year. It's not rocket science though. The number of millionaires are increasing every year because the amount of money in global economy is increasing every year.
Talking particularly about crypto millionaires I think crypto millionaires are increasing every year too because the number of people investing in crypto are increasing every year.
The crypto marketcap is also increasing every year which means more money is flowing into crypto every year making new crypto millionaires every year.
