Fuck you status has nothing to do with Bitcoin or fiat money.
It's all about attitude.
Just stop worrying about money and things.
I did it in 1976. It's actually easy. Just stop worrying.
Sure, sometimes it can get a little dicey but in the long term it'll work out.
Yeah you might have to go for a day or two without eating. Don't worry, you won't starve to death.
Don't be a crybaby. Everything's fine.
My reference seems to be a bit different than what you are describing, including:
1) I am largely referring to a chart that shows how to valuate BTC using $2 million as default entry-level fuck you status.
and
2) The valuation is using the 200-week moving average rather than BTC spot price in order to figure out when you might reach such status in terms of your BTC.
Sure, it is not necessary to have $2 million in BTC and you also could have other sources of income and/or wealth that you might consider,, and surely there are a lot of folks who could pull the fuck you lever with way less than $2 million, perhaps even $500k or even a lot less, yet if we might be considering a western lifestyle, from my point of view $2 million became the new $1 miillion sometime around March 2020 or soon thereafter.
And in the end, living within fuck you status should not bre a worry, as you say, as long as you are capable of having your expenses lower than your income, yet there still could be some questions regarding what percentage of withdrawal rate might be sustainable if your just considering BTC or if you might have some other assets involved, since no one should want to return to having to work once they have pulled the fuck you lever - especially they should not want to return to work merely because they failed to sufficiently/adequately calculate how much they need for fuck you status.. and yeah, there could likely be cases in which they actually need way less than they think that they need, and surely I am not going into those kinds of personal discretionary matters or even saying it is easy or not easy since guys are going to have to decide for themselves anyhow whether they have reached it and if they fuck up, don't come crying to me.. go see Jimbo instead, since he told you to do it and it doesn't matter if you are ready or not, everything will work out...
..
Maybe another key concept is being able to live off of growth (so profits) rather than eating into principle of the nestegg, which is part of the key to having sustainability in your stash size, especially if you might not know how long you might need to live off of the income from whatever the corpus of your investment is that you have saved.
Another side of financial freedom could have to do with wanting to potentially keep a higher standard of living, and maybe in some of those cases more than $2 million would be needed, and there have been several WO members who have made those kinds of claims, and I have even heard some folks proclaiming that $1 million had turned to $8 million, which seems a bit much to me, yet some folks want to live with higher levels of ongoing conspicuous consumption than others.. which is up to them regarding how long that they have to work in order to get to that status or if they will ever get there, even with the help of of such a pristine and appreciating asset such as bitcoin.
