Well, maybe we should define what we need for each to feel financialy free.
Let me give you an example. $50k/€50k is a very decent salary in Czech republic. It allows you to get three or maybe four decent vacations a year, you can put almost every meal on your table in top notch organic quality and probably you would be able to afford a new iPhone every second year no problem.
That said if you don’t have to pay $1M mortgage on your house or leasing for a car.
So I really think even 10 Bitcoin are more than a generational wealth. Don’t forget price appreciation in time and with little income from renting here and there I think you and even your children will be more than ok.
There are a lot of calculators out there available. And when I fed them with simmilar data you see above, 3-6 Bitcoins could allow me to retire somewhere around 2030-2032.
Not that I am anywhere near to have that much, but I am working my ass off to get there.
