Wow! Just wow!!
You must be a good orator and marketer to have convinced your old man to invest in crypto-currency having used Fiat much more of his life. I don't know the name of your country but if our older parents let's say from 60 yrs and above in Africa can give cryptocurrency a trial our Economy will boom but funny enough most of our youths still perceive cryptocurrency as scam.
How will you make your economy boom by investing in bitcoin? Bitcoin is not a get-rich-quick tool. What happens when the value of bitcoin drops 50%, and are you sure your parents will withstand that shock?
Cryptocurrencies are scams, created and disappearing projects like Luna and FTX are scams, and our youths are not wrong. Apart from bitcoin, all that remains is gambling and scams.
