For me its about balancing risk, like I buy Bitcoin because I am shit scared my local fiat can collapse at any second, its already lost 12% of its value to a declining dollar this year alone so fuckit, all in right?
But I still need to face reality that I have fiat bills and I don't want to ever have to sell my bitcoin or be a forced seller so having a cash balance I just see as buffer for that, I am willing to play the inflation premium to never be a forced seller at a price I don't think Bitcoin is worth
If ur not all in btc with every last penny scraping at the table for dinner scraps then ur not a real bitcoiner!!!!!
