Early retirement is bullshit for me, actually I'm stuck in this cycle.
I invest like 80% of my salary for many years, technically I can retire now because 4% of my investment is enough to cover my annual expenses. But, no one knows if I get sick in the future, my wife turn to be materialistic woman, school fees rise really high than 4% annually etc.
If I quit my current job and choose to the job that I want which likely earn bigger in the future, if I didn't make it, I will regret, at the same time I can't back to my old comfort job. Don't say take two jobs at the same time because the first job requires me to work for full time.
If you've been enjoying your job for decades and you've been able to support the family you have well, I think it seems like you're at least somewhat satisfied with the life you have, as if your entry into the bitcoin or crypto industry is just an additional source of income for you.
But not all employees are in the same position as you, and have the same good salary as you, and from what I see of you, you also seem to be good at managing your money.
And other employed people like you should be like that too.
