I would like for you to change your perspective for a little while.

Just owning one bitcoin would be enough for you to retire.
The price will easily go over $1,000,000 per bitcoin.
(and then it will crash down to a measly hundred thousand, and then go up farther)

Instead of retiring comfortably, you will be a multi-millionaire.
You could buy and build most anything you could think of.

So, what would you do when you find you have more money than you could ever spend? (bitcoin going up faster than you could spend it)

Would you put a camper on a deuce and a half?
Would you buy a retirement community?
Would you start a prepper town?

Just be sure to put into your plans that we are at the beginnings of a mini-ice age. Winters are going to get very harsh. Think about moving to warmer climates.
