I don't think I'll ever stop saving in bitcoin.

But thats not the question, it was when do stop washing dishes & start crafting 1100s style battle axes for sats?
I'm half retired and half retarded already.
Also, I wash dishes to clear my head. I don't use a machine, I prefer this form of meditation. My best ideas came to me while doing brainless jobs.
To answer your question, I don't really need much for myself. 10M sats 10y from now should be enough. Just as the bitcoin are mined in a spiral, so one should spend their stack when they decide it's time.
