I personally believe that we can live quite improved lives with BTC as our wealth, and it may well be quite likely that the BTC value will grow way beyond our spending pace, so if the BTC is allowed to compound in value a few more times, we may well end up with way more wealth than we expected, which may well allow us to go from spending wealthy and wise and into higher levels of extravagance.
It is like going from entry-level fuck you status (FIRE status), end then getting to a point that is multiples higher than the entry-level status, and then perhaps being 10s or even 100x higher than the entry-level fuck you status at a kind of filthy rich status, which some of those higher levels can come without necessarily having to work hard at it, but just living within one's means and allowing the value to continue to compound, which so far in bitcoin's history, it has compounded many, many times...
bitcoin will compound at far better rate than any bank account interest rate or portfolio manage stock options.. its just picking the target amount where the compounding is growing more then the withdrawal
can i just offer some advice.. the whole 'fuck you status' of just extravagance/burning money 'cos i can' gets boring quick.. dont plan on a wasteful spending as it wont make you happy long term
it only lasts as long as driving a car out the showroom and on the way home seeing someone with a car thats better than yours (less than a couple hours)
where your then already thinking 'maybe i should have bought that one instead'
i actually enjoy knowing i can buy any car, any house.. but just not needing to.
the peace of mind of not having to worry about money is the essence of F.I.R.E, its not about buying crazy things 'because i can'
its not about forced frugality either
.. in short, once you reach F.I.R.E status. your mindset will change about whats important to you. rich/extravagance gets boring.. you start to want to have and explore experiences, not shiny objects
