What to do with Btc after retirement?

I have some Bitcoin now. Not enough to retire solely on Btc alone, but enough to use as an added savings along with my traditional retirement accounts.

Obviously after retirement, fluctuation in the market could really hurt my plans and I want to protect myself.

In the 20 or so years when I retire, would it be best to sell off monthly/yearly amounts or sell it all off at once to keep my comfortable lifestyle?

I am not a Btc fanatic and I do not believe it will replace today's currency in my lifetime but am using it as a hedge to compliment my already setup retirement plans.
