I work at Bitkit, a self-custodial Lightning and on-chain wallet designed to feel as easy as custodial. Yet we see the same pattern: some bitcoiners are fine with custodial, some won’t touch it, and others base it on the amount.
I’m in the “don’t give custodians and old ways an inch” camp, but I get the convenience factor.
What’s your line? A spending balance, a percentage of your stack, or zero?
