However, if you are in your bitcoin accumulation process and have not reached your bitcoin target, it's impossible for you to say that you want to live on your bitcoin investment, because you need a job to continue accumulating more bitcoin and anyone without a job will not be able to invest in bitcoin and grow his portfolio, which will make you start selling too much of your bitcoin, too quick and you will regret your actions in the long run.
Even if you have reached your Bitcoin accumulation target never say fuck you to your main source of income. Whatever the level of knowledge we think we have acquire its a huge risk to quit our job. 90% of success in Bitcoin investment is long term, consistency and patience. Instead of quitting why not we continue a stable investment to live off or save for a business that you can rely on. The only time i can agree to someone quitting his job is if it is not a good paying job and when an individual has made enough to retire.
It seems to me that you are misunderstanding what it might mean to reach fuck you status, and surely you realize that you can quit your job if you have made enough to retire, so why is that different from quitting ones job when they have enough BTC?
For sure, the more BTC you have the more options you have in regards to income off of it, and there could be errors in calculating the value of your BTC, so surely there are a lot of examples of people who pull their fuck you levers way too early because they miscalculate how much BTC they actually need in order to live off of them and how to valuate them and to valuate their standard of living expenses (or increases in their standard of living due to debasement of the dollar/fiat or from chosen increases of lifestyle expenses).
I am not a job person, so if i reach my fuck you status in my Bitcoin accumulation then it would be very much easy to quit my job and retire, basically my retirement doesn't mean i am off with using other sources of income not just relying on living from my holdings. The shot there is to take profits, reinvest into basic marketing or business without any stress.
In terms of misinterpreting/miscalculating the level of profits attained is a subconscious feeling when the investor tries to evaluate according to what is present and with less or no calculations on how the future will look like, from selling off everything and just basically living off the whole sell figure. Huge economic slow down might happen, inflations and crisis which will alter expenses on living, drastically there will be more to take from what was kept aside from what was calculated, more to that we also believe emergencies are prone to happen at any point in life. I rather not claim to retire, then fall back to working once more to raise my living expenses, if i am not old of age to retire fully then i might still continue contributing to my sources of income just something to work independently.
