It’s worth noting that this isn’t the easiest calculation, and getting an exact number is quite challenging. Bitcoin will remain in your portfolio over time. If we begin selling from 2036 at $100,000 per year, in roughly 10 years we could safely increase annual withdrawals to $200,000. Approximately every decade after that, it should be possible to gradually raise the amount of Bitcoin we spend in dollar terms, keeping a stable and growing passive income.
