I'd never sell it all unless I'd also lost conviction in its future. There are price points where I'd trade some sats for the things I desire. There are prices where I think I'd rather have a little more fiat than I currently have (near zero right now). It was when I realised that I didn't want to sell it all that I actually went all in (except for the family home). I just prefer to hold Bitcoin than any other form of value.
