I've had a few people recently ask for my advice on how to think about "retiring on bitcoin". I hadn't thought too much about this before, but there seems to be an emerging niche of people who suspect based on their current bitcoin stack and growth assumptions they should be able to "retire on bitcoin" now or soon. In these discussions people expect to meet their cash needs by either 1) selling a small portion of their stack regularly or 2) borrowing fiat collateralized by their stack.
It seems like a fairly complicated question to model properly though: e.g., What are your cash needs today and how do you expect that to change in the future? What are your bitcoin growth assumptions? What kinds of drawdowns/bear-markets do you expect to sustain? How much buffer should you build in to ensure you are resilient?
Any links to good writing or calculators to help think through these considerations? What other factors do you Stackers think should be considered?
