I'm still working, so I don't have much free time 🙂
When I have it, I'll know how to fill it, I won't miss work.
The only question is at what level it will be...

As for financial security and safety for retirement, time will tell if investing in btc was a wise move 🙂
It would not be wise to rely only on the state pension fund (but also on the private one that I have for after 65...).
If my investment in btc fails, it will be an average worker's pension...
