Best way to retire on BTC

Just had my 40th recently so am perhaps getting a bit ahead of myself but how does everyone see themselves using BTC during the retirement phase of your lives?

If you are here already guessing you have or will have a bigger stack than most people, so what plans do you have for actually using BTC to retire on? Know in an IRA or 401k to withdraw in dollars they have to sell the assets, is that what many of you are thinking of doing? Or just taking loans out on it and waiting for the valuation to overtake the interest rates, preserving the inital balance? Or some other way?
