If I want to “retire” in 5 years, how much Bitcoin should I have now.

Retire is in quotes because I’m in my mid 30’s, so what I’m really talking about is financially independence.

I can live on less than $50k a year. I’m looking to replace that, but not live extravagantly. No Lambos.

I have other assets like real estate but for the sake of this hypothetical let’s assume I don’t. How much BTC do I need, and what’s my game plan (borrowing against it, etc)?
